Came across one and want to be fair (but may be out of my range), but don't know enough.

You'll want to make sure it has two screws to lock the altitude setting. If it doesn't, HGM will retrofit for a reasonable fee.

So, assuming what you have found is the "G-11" made by Losmandy for Celestron, then everything should be upgradable to current specs...but for the definitive answer, call Scott at Losmandy and ask. AFAIK the upgraded worms fit all G-11's, regardless of age.
If the mount has the Gemini controller, then it is likely the older style - which meas you will need a relay box or optocoupler when interfacing to most autoguiders - not a big deal.

You'll probably want a newer polar scope.
If you bought the stepper version new for example you would get the SAIA motors, you would get brass worms, you would get the second altitude lock, all for around $2200 to $2400 depending on options. You might sell it five years later for $1800.
You're looking at $500 or so in upgrades to get your older version up to the standards of a newer used model.
