Not Cessna or Piper, but I can also recommend the private school associated with Bae, hired an aircraft from them last year. The aircraft (Tobagos) can be a little hard to get hold of if the college is busy, but are very well looked after & not rediculously expensive....not back then anyway! Apparently they've also recently got a Diamond (the 4 seat one - DA40?) online if you wanted to try something new!
Flying schools aside, it's a great state to see a little of from the air... Have fun!!
