Mark_ms,
I spent a month at Blue Sky Aviation in Venice on the gulf coast of florida this year.I found it to be the cheapest for what i wanted which was to purely build hours.They only have 3 C-152s and 1 Warrior but a/c availability is never a problem.Accomodation is nearby and staff are v friendly.Check their w/site for prices or pm me for more info!
Cheers
PP
