I have a lightly used Argo Navis Computer for sale. I've used it a couple of times and it works great. I've discoverd I'm not really a DSC person. I work with computers all day and want to get away from them at night, simple as that.
If you're not familar with this computer do a web search and you'll find lots of info, or email me with questions.
If you have a Losmandy mount I can include encoders and hardware for an extra $100. I'll be running a separate ad for those when I figure out how to remove them.
