That's a great tip for alignmaster! I'll be sure to sync this with the Gemini bright star list and make an update for my setup.
When I use alignmaster with my Losmandy G11 with Gemini 2, I can get within 2 arc minutes on the first pass and under 1 arc minute on the second pass. The rest is gravy as the threads on the adjustment screws are too coarse to get better on a temporary setup.

it's nice that the star list can be edited, because my list of candidate stars from my balcony is alarmingly small.

It is, at least in my world, very portable and delivers unguided performance that is excellent.
I have an unboxing review on SGL (http://stargazerslou...00hps-unboxing/)

but the OP is in the US, so..

I'm looking for a high end mount in the future around 5k used or new. Portability will be a major concern, as I will be setting up and tearing down every time I use the mount. I will mainly use the mount for AP, thus accurate polar alignment is paramount for me. Which mount in this class offers the easiest and most accurate alignment procedure? I really want to avoid drift align as much as possible. I understand the Taks have awesome polar alignment scopes, but the Mach1GTO appeals to me greatly since it can handle a bit more capacity than the EM-200 and handles cold better...however, my understanding is that the polar alignment routine with Mach1GTO stinks in comparison.
I have a Mach 1 and I'm using Alignmaster as well. This seems to work very well. I usually do two iterations and there very is little left to correct, for guided imaging anyway. Like others have mentioned, the given selection of stars may not visible from a location, many are blocked by the large trees in my yard...nice it can be edited.
The important thing here is the OP isn't going to find a Mach 1 complete with tripod and accessories for 5k used.

I was tempted to just pay for it sight unseen, but I have no idea if I'll instantly get a key when I do that. I think the author manually generates the keys or something...
That said, you can get a Mach1 used with tripod and accessories for close to 5k (maybe 6k total) so long as it's not one of the pricey AP tripods (AWT00 or Eagle).

I have not used the new right angle polar scope and I will not for two reasons: 1) The mount needs to be perfectly level in order to polar align.
This is not correct. N-S leveling has no effect on the polar scope, and E-W leveling would have to be "really really off to make much of a difference" per Roland in a recent thread on the subject on ap-gto.
Ok Paul you convinced me! RAPAS on order! I actually spoke with two people who use it and they both gave stellar reviews.
