The trouble is that you have probably spent too much time in aircraft that have had next to no investment and maintenance and so the fading paint, old avionics and carpets that smell as if some sort of pond life in in residence, in short you have been ripped off!
I could show you places that do invest in the aircraft and PA28's & C152's that are very nice to fly. Clearly you don't understand the qualitys of these aircraft and the skills that they could teach you.
PS take a look at the Airways Flying Club's latest PA28 avionic fit!
