Wait a second.. I stand corrected - It is the same seller, but in two different states? - I never noticed anything like that before, but I guess they must be a network of sellers working as one. They appear to do major business and a 99.7% feedback out of over 2500 transactions does appear that you wouldn't have to worry about bidding.

edit..
the description says "I was using this unit to cover about 1/2 our small town, but we just got a FCC construction permit so I'm selling!..." and goes on to mention about part15 and ect... sounds very first person, -- but what's the story in listing the same item only within only about a weeks time span from two different states??
Nevertheless, if I was planning on bidding on the unit, I probably wouldn't feel too hesitant about it.. but it's still very curious!
