Awful design feature.
Matter of opinion!
Had electric flaps on our Rallye and on the Cessnas I've flown (150, 152, 172, 207)
The 'handbrake' deal is simple and honest. We had a potentially nasty accident with our Rallye with flap over-run with a sticking switch and I've experienced the same with 172s. The electric mechanism has also been known to become undone with the potential for asymmetric flap.
The Piper Cherokee 140 is as Maude Charlee says an easy aircraft to fly but the stall is relatively more pronounced than with the later Warrior wing. It'd be well worth your while doing a few en route, clean, part flap & full flap at idle and 1500 RPM. The a/c tends to be a bit more precise in the flare than the Warrior, which can float on and on...
stknruda,
Someone of your calibre shouldn't have any issues at all. The PA28-140 is cleared for spinning (check your particular a/c first!) unlike the later Warrior so you might be able to have some fun with it, after all. Never tried it myself.
Cheers,
