Leon,
Don't discount a 3 - 5" table top dob.. that would be in price range I think...
Easy to live with, easy to setup but, will obviously need some sort of table...
I can't speak with first hand experience on TT dobs specifically but, my little Vixen 5" Newt is an absolute killer & you only have to look in my signature to see what I'm comparing it to...
Just a thought
Cheers
