He didn't ask for charity, $155 is a reasonable start for used equipment and I think that's been well established for those interested but have a limited budget. I talked extensively on the phone with the dad and didn't sense anything greedy in his nature, and he was happy to find a $175 Tower trainer right on RCU and in his area. He said he was going for that plane. Therefore I think his purpose in posting came to a successful conclusion.
$155 in rural GA might be big bucks to some.
