Scored big time with that deal. Used dobs are honestly the best kept secret in this hobby because people drop serious cash on fancy gear thinking the scope is the problem, then sell the good stuff cheap when they get bored. An 8 inch dob is basically a light bucket that shows you galaxies, nebulas, and Saturn's rings like it's nothing, and no $400 starter kit on a shaky tripod can touch that. The mirror is what matters, not the price tag or the brand name on the tube. You basically got a lifetime scope for the cost of a nice dinner, and now you can put money into eyepieces or a better finder instead of replacing the whole thing in a year.
