There's been a lot - and all but a couple died or were broken/out of service then thrown away...
Grundig Mini 100PE - first time I heard shortwave transmissions, around 2003. Mostly listened at night when 31, 41 and 49m were strongest.
unknown shower radio - 2004. At least I could listen to my favorite music while taking a bath as a kid! I also discovered AM DX through this cheap radio. 1510 'The Big Talker' KGA, 1530 KFBK Sacramento, 1160 KSL Salt Lake City, 780 KKOH Reno, etc.

My dad had a Sony STR-DE545 stereo/home theater receiver in the living room...one night I played with the AM loop antenna and heard KNZR-1560 Bakersfield and KZNY 'Sunny 1520' Portland.
Grundig G1000A - 2005, another cheap Grundig portable with a digital display, but it was well-known for drifting off frequency at times. Good memories of listening to Radio Australia and Radio Taiwan International English broadcasts on this one. Also introduced me to those 'Firedrake' Chinese jammers.
Grundig S350DL - 2006. While it looked fancy, the FM was absolutely awful, bleeding everywhere. Shortwave and AM did OK.
Bearcat 210XL - 2006, first scanner, came used from a thrift store. This also included a HUGE telescopic whip antenna, probably 5 feet! Lots of good memories on this receiver. Always heard State Patrol every day, several school district transportation departments, local police, etc. living in Bothell.
Grundig G5 - 2007, this cost my family $150! This was the first of two G5s I had, used, torn and abused for years. The FM performance was better than any radio I had used until then. This was the radio used to receive KTRA-102.1 NM on 7/29/2007, which was the first time I had ever heard e-skip. I had actually been listening for KSWW Aberdeen (Sunny 102.1) since our family had just taken a trip to the Washington coast and they had a better mix of soft rock than local Warm 106.9. I still use the 2nd G5 as my primary AM receiver because it's so good! All of my 2009-2011 Es logs were received with this radio. This also went on another Washington coast trip and trips to Yakima and Portland.
Grundig G8 - 2011. Another superb radio, especially with FM separation. All of my 2012 and 2013 Es logs were received with this radio. (2012 logs from Bellevue, 2013 logs from Monroe) Then the antenna accidentally got busted and even with a new antenna the performance wasn't good, plus it had been used and abused. The speaker was pretty tinny as well.
Tecsun PL-660 - 2012. I dealt with a lot of bleed on FM, but the performance on AM and SW was decent. Long whip antenna too! Most of my 2014 Es logs were received with the PL-660. I don't use it anymore, once again the antenna got busted and the tuning knob broke off...*man* am I abusive to my radios!
Grundig G5 #2 - 2014, the first one finally died and I was able to buy a used G5 off eBay for about $50. The performance was just as good as the first one, with strong FM reception. I still use this one as my primary AM receiver with the 3-foot loop. I built that loop in late 2012, with a variable capacitor, 8 turns of wire and PVC pipe. Most of my 2015 Es logs were received on this G5. This has also been used and abused but it still functions quite well.
Radio Shack DX-402 - 2016: my primary FM receiver. Had it sent to Bruce Carter in Houston for narrower filters (150khz), it works very well. This has been taken on several trips throughout central and eastern Washington and still does well. At least the whip hasn't been broke off. 2016 and 2017 e-skip logs were made on this radio, and probably some of the 2018 logs too once we get to late spring. This is the radio that netted me double hop from Waco TX last June along with a 100w LPFM from California, a 250w translator from Yucca Valley CA and many, many other stations.
Radio Shack PRO-51 - 2018, a used early 1990s portable scanner. I'm just using the rubber duckie antenna but I will be changing it out for a 2-foot telescopic whip to get better reception of Lower Valley/Ellensburg/Tri-Cities scanner frequencies.
To be bought this spring...an AirSpy HF+ SDR. I am also purchasing a small 3 or 4-element FM antenna that can be put on a tripod. I'm going to try out an SDR and an external hard drive and see how it goes for Es. I am still using the DX-402 for mobile sessions and trips.
Would also like to try out the Sangean ATS-909X, I've heard this is one of the best portable FM radios. The RDS keys up very quickly.
