The tower hobbies or hobbico trainers are a good way to get back into the hobby, though whatever you do, you should get involved with a club and see if a trainer can take you up to re-hone your skills behind the stick, or develop new skills.

Also, I would check craigslist for south FL, as there are usually lots of planes for great prices advertised there. Likely by the end of setting up an RTF glow plane, you'll end up spending enough to buy someone's used rig with a much nicer plane than you originally intended, another reason to see if there is a club where you can re-hone your skills on a club (or instructor) trainer.
