Since your equipment can already get Dallas under good skip conditions, obviously it won't take much improvement. While an APS-13 is an excellent DX FM antenna, it will set you back some serious money. I found an antennacraft FM-10 for $50 one time - it has 13 dB of gain. If your tuner at home is already doing Twister, 91.7, 104.5, and 94.9 (which amazes me given there is a 94.9 in Wichita Falls), then you probably don't need a new tuner, although a DX model would help. All in all - if you can find the Antennacraft FM-10 somewhere, get 20 feet or so of mast at Home Depot, a wall mount for the mast on the side of the house, a matching transformer, and some 75 ohm cable, you are probably looking at much less than $100. Find some junk metal pipe, kludge the mount - probably less than $75. Pretty cheap for a decent deep fringe FM antenna - especially when those junk trendy indoor antennas are $50.
Given that Power FM is up 1700 feet, you've got an excellent chance! I had my yagi up no more than 15 to 18 feet in the 1900 block of 27th, and my biggest problem was reflections off of that apartment building nearby. It gave me multipath on Dallas stations, which should be an indication of just how strong the signals can be over Lubbock! The 14kW should not be much of an issue - it is the height of the antenna. They are up 1700 feet, or 2400 above sea level. You are up 3000 feet above sea level with what amounts to a basin between you and Dallas - greatly extending your ability to DX.

If you have problems with 1st adjacents (and even if you don't), you can soup up your tuner and make it much more sensitive with the narrow ceramic filter trick. VERY inexpensive and VERY effective. It makes even modest tuners real DX machines as well as eliminating all but the strongest first adjacents.
I am only in Lubbock a few times a year, and I am considering putting up a deep fringe antenna at my father's house. I have an old Sansui tuner sitting idle at home, it is more than up to the job. This isn't that difficult of a challenge. You will get deep fades, especially in the middle of the day. But mornings and late evenings will be pretty solid.
I'll tell you what - I'll swing a yagi your way and see if I can get things like cool 98.1. I'll let you know in a few days - it will probably be the weekend before I can do it.
