I found mine in the garbage, with neither eyepieces nor power supply. The mount and focusser needed a little TLC, I borrowed eyepieces for a few years and have now bought my own, and use one of those all-in-one AC adapters for power. I also had to modify (well, replace) the EP holder to take 1.25" EPs.
Perfectly useable scope! I have seen wonders galore using it, and know it will continue to give me joy for years to come.
It's VERY important to get good alignment to use the GOTO I've found. There's a couple degrees of play in both altitude and azimuth that I can't seem to get rid of. The focusser works, but needs improvement or, preferably, replacement. I'd also like to upgrade to a 495 or 497 hand controller, to make it easier to hook my computer up to the scope. The finder scope completely sucks, but is "useable". I must replace that, sooner than later.
I've used it a little for astrophotography even, mostly limited by my *BLEEP* web-cam. Just the Moon and Jupiter so far.
Anything else you wanted to know?
EDIT : seriously? bleeped for that word, started with a 'c'?

If I cannot be bothered with the alignment I simply level the scope, point north and tell it to do the easy align and simply say OK when the scope stops at what may or may not be the 2 alignmnet stars.
At least then when I drive it to something the scope tracks fairly well so the viewing is longer before adjustment is needed.

First off, it's important to have the scope balanced decently. I like to have mine slightly front-heavy as opposed to neutral for a more positive drive engagement. My observation is that I get better tracking that way and the eyepiece stays at a more comfortable viewing height. You also need to calibrate and train the motors, which is a fairly simple process.
It may go without saying, but I've found that to rarely be true, so ... You've also gotta have your Lat./Long., date, and time entered accurately.
Once you've got that, it's rather simple. I always do the two-star when I actually align.
I pick two stars with quite different sky locations. Say one at least 65 degrees high, and another closer to 20 or so, and at least 100 degrees east or west of the first star. I'll align on the two stars, then tell the scope to slew to Polaris. If it's too far off, I re-do the alignment. If it's ok, I slew to some other bright star, then hold down the 'Enter' button to put it into 'correction' mode (that's not what it's actually called, sorry). This turns off tracking temporarily, and asks you to center the object, then hit 'Enter' again. Basically, it corrects GOTO and/or tracking errors a bit. I often repeat this on different stars, GOTO-ing them, until I'm happy with how centered the requested object is. Usually doesn't take more than 2 tries, tho I've had to do up to 5.
Using this process, I have left the scope tracking, unattended, for up to 4 hours and come back to find the object still in the eyepiece.
Sometimes I just use it un-powered for simple Lunar or planetary viewing. Other times I power it but don't bother with alignment. Quite nice so you can use the handbox to move the scope instead of trying to nudge it around by hand.
If the scope's in decent condition and a good price, GO FOR IT!! You'll be pleased I think.

and looky looky what I found, from the cloudy nights archive LOLz

The long narrow tube across the top is my initial attempt to make a camera mount for the scope. It is currently under re-consideration and re-construction.
My modification to accept 1.25" eyepieces:
I added this bubble level from the local hardware store too:
Hope that helps, or is at least interesting.

of course, seeing was EXCELLENT that night. I've looked at Jupiter up to 220x as well.

I will be trying to control from the computer very soon. Have you had any problems or do you have any advice that might help me setting it up for my first time?
