Jase,
I wouldn't take "the list" too seriously

Also it depends how old the Titan is. The current crop have changed to Phosphor bronze worms and there have been a few other tech changes. I understand the last production batch had +/- 3 arc sec raw PE as a result....
That said for heavier payloads, I would in fact pick an AP1200 any day. While it is priced a good deal more it is physically larger and will indeed hold significantly more telescope and return a similar level of tracking performance.
Steve Crouch is using my old HGM200 these days and getting some great results from it....in fact I miss some aspects like being able to track for hours past the zenith which the PME can't do.
But I agree entirely, with the "horses for courses" summary. You'd be nuts to think a PME is required to adequately point a 50mm camera lens when an EQ3 would easily to the same job.
Cheers
Peter
