2)  How does the TruTrack Sorcerer Autopilot compare with the STec 55X in capabilities?  Which/what autopilot would you recommend based on your experiences?
 
 I can't speak first hand of the sorcerer (because I haven't flown mine yet) but I do have a 55x.
of the 55x I can say
    - never solved the porpoise problem when tracking a glideslope at low altitude.  granted this is on an unusual installation - a c172RG.....oh, a IVP is sort of unusual too isn't it?
    - it took me almost a year to debug the (rest of ) the installtion.  turned out to be a broken plastic housing on a dsub connector.
    - factory support is abysmal
    - rate controlled is great for reliability but it's a rough (strange yawing motions and short term heading deviations) ride in turbulence
    - doesn't have speed hold mode in climb (vs. vertical speed hold)
 
In short, if the trutrak does even half as well as I expect I will be happy not to have another stec product
