Sorry if this topic has been broached before, but I couldn't find anything using the forum search. I've got an Alt/Az mount right now but would like to get a cheap Non-GoTo equatorial mount with motorized tracking for high magnification views of the planets. Does such a beast exist?

I suggest that you get an Orion Sky View Pro mount and add an Orion tracking motor. That's your cheapest solution, probably.

What scope are you putting on it? The XT8?

I was thinking my 80mm refractor, although the XT8 would definitely be a better planetary scope. I just figured it would require a pretty beefy (and expensive) mount. However, I would like a mount that would be somewhat future-proof, capable of supporting say a four or five inch refractor.

Used CG5 or LXD55(Celestron-Meade), or nongoto version of the same with RA drive and a used Orion Sky Wizard, Meade Magellan etc.

Go for a CG-5GT. It will be cheaper in the long run. An XT8 newt will "work" ok on it, but you still might have a long settle time, and it will move slightly when the wind blows at any rate. This mount holds 4in short tube refractors well too. It's the "moment-arm" or length of the scope you must keep in mind. The CG5 is rated at 30lb, but a 20lb load is perhaps its limit. :)

Yeah, after doing the math on the Orion Skyview Pro and drive, it would probably make more sense just to spring for a cheap GoTo like the CG-5GT. I hear it's pretty noise, but that's just when it slews during the GoTo process, correct?

If you don't need GOTO, an older CG-5 - type mount with a RA drive or dual drives would do you well, the drives are pretty quiet, and for visual use, they keep the scope plenty steady enough.
You could also watch the classifieds for a Vixen mount, A GP or SP, they are the 'real' ones that are copied by many other makers. My 80mm rides comfortably on an 'antique' Vixen Polaris, the smallest of the three. Also, the Polaris is well-regarded as an alt-az mount, mine often runs in that mode, because it is my 'guest' scope, and newbies find alt-az easier to understand.
