Leading Edge is pretty good...I'm from Ruskin, and rented there a few times to take my dad flying. I don't know much about their instruction...all I did was a rental checkout. At that time, they had a good selection, and you could choose from anything from a 152 to a 172SP depending on your needs and budget. VDF is a nice little airport as well...practice area is close to the east, and Tampa's airspace is close to the west if you want some busier ATC practice.
