asa31798,
I own a Losmandy GM-8. It's great. When I was searching for one I summarised what I learned at the time:

I use the mount regularly as the base for my portable setup. I find it very good, quite a joy to use, easy to polar align and all that. I haven't got the newest version of the Gemini software, I believe it improves the PEC amongst other things.
Happy to help with any specific questions if you have them.
Roger.
