Here's my Genesis SDF that I bought new back in the 90's. I was heavily into the hobby back then but "Painted wings and giant rings make way for other toys", in my case it was guitars. I still take it out once in a while and it performs just as it did when it was new many years ago. Design wise it doesn't look dated at all as others have said the build quality is second to none. The only thing I added was a JMI MotoFocus which also still works after all years. It could use new case though, the latches don't work that great.
I have thought about selling it a few times, but now I think I'll keep it. Whenever I set it up for public viewing it's a blast to see people react to seeing the moon and Saturn for the first time. I live in New York City now so DSO observing is out of the question unless I travel, but the moon and planets are still satisfying.
Here are a few pics from the 2017 solar eclipse. Look at that line, nothing draws a crowd like a telescope.
