Hmm, I see an 88 in that list. I sure wouldn't mind having one of those again. Dare I ask how much you're asking for an 88? Granted it was years ago, but the last one I had I sold for over 4K. It did have a G-138 scan head attached to the end plate though. The 88's are a great laser, the one I had was quite old, only had 500 hours on it, started up everytime and put out 2.2watts.
