So close to me i have a chance to buy a about 20 year old 18 inch stamaster f/4.3 with zambuto mirror. coating are in great shape and it has servocat, argo navis and shroud. The guy (second owner) rebuilt the rocker box and braced it with metal angle brackets. He is a woodworker and furniture maker. Comparing a 18 inch obsession to 18 inch starmaster the starmaster does seem to have a higher rocker box and mirror box. The argo navis has developed a hiccup that wasn't there before i am told. he thinks its just a battery problem but he is working on it. He is wanting 8,000 for it. Has Sent me pictures and all looks very good including the rebuilt rocker box. He is the second owner. So what is a fair price to pay. I have done alot of looking for what others have sold for but was wanting more input from people to get a more rounded view of what to pay. Thanks for any help.

Used 20” Obsessions run around $4,000.
With the drives system that would add $1,500-2 maybe-but it’s quirky….The Zambuto is huge win though… I think $6,000 would be pushing it. 5.5k -5k might be what I think would be reasonable for a 20 year old 18” scope with a killer mirror.
