I'll do some more research. It seems there are a lot of good companies out there. However, from what I hear, and from what my CFI and the people at windsock said, David Clark is pretty much the best out there.
By the way, I was flying a 152 for about a year and a half, but just switched to the 172SP recently. My flight school as 3 SP's, one of which we just got last week. One of them is 99, and the others are 2000 and 2001 I think. At least 2000 though. And yes, all equipped with leather, GPS, AP, the works.
Honestly, I always thought it would be fine with just a coupla instrunments, and that everything else was just......extra. Then on Saturday, when we just took off on our last pattern practice, the emergency panel flashed "volts" or "voltage." Our charger had failed, and our ammeter showed below 0. If that didn't flash, I probably wouldn't have noticed the low on the ammeter, and within 30 minutes, we could have lost radios. We just turned off any unecessary stuff, like strobes and stuff. We were in the pattern for landing anyway, so we just continued what we were doing, and came back in with a greaser.
