3.) Keep what I got until Jared gives me his Mach1 GOTO. Ha, ha.
Sorry, I still owe my wife two to three hundred favors before the Mach1 is fully paid off.
By the way, while I have never tried imaging with a fork mount (or at least not recently), I used to use an AO-7 with a Losmandy GM-8 that had periodic errors that were too fast to be guided out very well. In practice, I never got quite
as much resolution with the AO-7 and mediocre mount/tracking as I have been able to get with the Mach1. It certainly came pretty close, though... And it was dramatically less expensive.
As one or two others have said, I think the real advantage to the high end mounts is not
that you will necessarily get better results, but that you will get them with less effort. With the Losmandy and AO-7 (admittedly loaded to 25 pounds) I would need to make sure worm was adjusted perfectly, balance was perfect (a few ounces East heavy), backlash set correctly, guide star was bright enough for a high sampling rate... With the better mount I can skip all that. Is the balance vaguely correct? Cool. Just turn on the autoguider, and I can be assured that I am limited only by seeing.
