I have a CI-700 with the advanced astromaster computer. It has a few cosmetic dings but works well. I have used it twice and it appears to be in perfect working order. I am selling it because it is just too big for my tastes. For those who do not know this mount, it is rated at 60lbs and weighs a little more. I am looking to get a Losmandy GM8 instead. It must have the current larger saddle(not the older version). I would also really prefer a local trade or close regional trade. I am in the Denver area. Let me know if this sounds intresting to you and we can talk.
