Jonnyboy102 - after about 250 hrs in PA28 series (Cherokee 140, Cadet, Warrior, Cherokee 180, Archer, Arrow) N-, G-, F-, ZS-, and C-reg'd aircraft, the only real "tech" problems I can recall are a sticky starter motor in FL, a busted nose gear oleo while taxying in SA and a dodgy transponder in GB. Not much really. As mentioned, PA28s are built like tanks and handling-wise are very forgiving - if a little boring in the long run...
