I couldn't agree more.
The quality of GA avionics varies hugely, and autopilots tend to be at the crappy end.
You can read about the KFC225
here 
And that cost about 2x what you paid for yours.
Interestingly, when Avidyne (a company which BTW is all words and very little action nowadays, with desperate new product promises and cash-up-front deals for discounts when Box X is certified etc all suggesting they are very short of cash) started doing their DFC90 autopilot, they were going to use STEC servos, to ease the certification process. But Avidyne have recently
announced that they are switching to the King (Honeywell) servos.
In the meantime Honeywell show no sign of wanting to fix their defective servo design whereby the amplifier self destructs if the current limit is activated for more than a few seconds. Their new SB11 just shorts the current sensing resistor with a piece of wire
The Honeywell servos are mechanically very good and much better than STEC's but their electronics are rubbish.
The bottom line is that most GA avionics firms have very little in the way of brains in there. I suppose the pace of new product introductions has been so slow that all the smart people moved on years ago.
