I do not regret selling any of them. I only sell them when I bring one home in the same power that I determine performs better than another set I already have. I also only purchase them if I think there might be a potential chance to upgrade.
I currently have a small 2nd hand lot of consisting of about 7-8 that I consider keepers, But any of those keepers may be shipped out if I bring home another new find in a same power that happens to out perform any in my collection.
I'm in a different boat than others more serious, because all mine were purchased 2nd hand and I never spent a significant amount on any of them. However I do have a few finds in different powers that I really enjoy.
A couple months ago I got the chance to look through a very expensive pair for the first time, and was able to compare it to what I have.
I will admit they were definitely better than what I have, but they were not within my budget. They also were not what I consider $2000 better at this point in time. At first I did not even initially see all the differences, and then the owner of the pair told me different things he noticed, and after they were explained I was able to see what he described. (It was basically a exercise in looking for faults, and not just enjoying the view). But I guess once you see the faults, they are harder to miss.
I'm pretty happy with what I got, but am always looking for another potential cost effective upgrade. Over the years I have sold close to 20 of them. When I do sell a pair, I usually make a small $10 -$30 profit so its not a hobby I really lost any money in.
If I ever purchase a bum pair online that I can not fix, I just dissemble them for parts and get a few telescope eyepieces to play with.
