Welcome, and congratulations on deciding on an 8" Dob! I have the Bintel 202 and really really enjoy using it! Beautiful views of Moon, Jupiter, Saturn and Venus and also you can see Uranus and Neptune (of course, there is not alot of detail there, and it is NOT easy to find them!) I sincerely doubt that you'll have much problem with any of the scopes you mentioned and they will all perform well. Enjoy!
