I have owned the TSA102 for quite a few years now. The cool down time is well around 1 hour and that might be too long. The scope presents superb pinpoint stars and it is well corrected. I use it for my primary widefield imaging telescope but every now and then I use it for visual. Lovely piece of craftsmanship.
I have not looked through the TV unit but being a doublet, I would suggest this will be a little inferior to the TSA.
Best of luck with your choice.
