From the look of those numbers, I would be extremely hesitant about going with this operation. If they can wetlease a 172 or a warrior for THAT cheap, they've got to be cutting some major corners (maintenance). Plus with 30 bucks for instruction, odds are the company is pocketing 20 or even 25 of that, so you'll have a CFI with you who's living in extreme poverty. He might even be in that trailer with you.
