All I can say, is that if you can remotely stretch to a Mach1, do so. (And you need neither the handcontrol nor the RAPAS for imaging).
It was an agonizing purchase for me, because it was way more than I had wanted to spend (it came to about $7,700 shipped with a tripod (3rd party--Avalon T-110), mounting hardware, 3x9 + 1x6 CW's and APCC standard and PemPro). Plus I was trying to make up my mind between MyT and Mach1.
I have been using the Mach1 for almost two years. I have zero regrets. People keep talking about the carrying capacity--well, carrying capacity (and the Mach1 has plenty) is not the reason why you buy this mount. There are more beastly mounts out there. Nor are the aesthetics, although it's a beautiful mount. But there are so many little things that just make imaging SO much easier.
Like the rotating base that makes PA a breeze.
Like the through-the-mount cabling that eliminates all the dragging cable worries and/or hub obsolescence worries.
Like being able to balance it to within an ounce or so.
Like not needing to worry about East-heavy.
Like being able to just slew to a target after just PA and have it be close enough for plate-solving (not blind!) to work every single time, with no more than a 2nd try to be within 10px.
Like being able to start with CW's in *up* position for those who dislike meridian flips.
Like never worrying if meridian flip will work, for those who *like* meridian flips.
Like having built-in wifi so you can control it with your smartphone and Luminos or Sky Safari.
Like having *knowledgeable* and *quick* customer support for the few cases when you may need it.
I am always the first one to start imaging on any night. I polar-align with Sharpcap (2 mins), slew to one star near meridian and equator to focus main camera and calibrate PhD2 (about 5 mins), and then I have SGP start the target and go to sleep. I used to worry about going to sleep because of possible glitches with guiding, etc. I no longer do. There just aren't any.
