Bob,
I can't comment on the 9mm Glocks, but I just got into USPSA shooting about 18 months ago and recently switched from a Para LDA to a G35. I really like it, and while I don't get much practice I am slowly getting a little better with it. I went with the 35 just becuase I already had all the stuff to reload .40s and didn't want to add another caliber.
If you won one, and I don't know what the upgrade fee is I would say go for the 35 as you can trick it up for limited with little expense or still shoot it in production if you don't want to make lots of mods. There are lots of threads here on that subject. The 22s are nice also.
I don't know where you are in Texas, but if you are in the San Antonio area and make it to any of the matches around town you are more than welcome to try mine.
Good luck with your decision and welcome to Texas.
