Megrez vs. RR

How does an WO Megrez (80 or 102) compare to a RR
( http://www.so-nl.nl/ ) refractor (83, 104/105)?

I never looked through a Megrez, but have a RR 83/500. It's a well corrected achro, fully coated. Very little color on the Moon and other objects. After you buy lens and cell,focuser, diag, etc. you save about $75.00- 100.00. I think you get a scope in the same leauge as Megrez, Stellarvue optics wise. The rest of the scope depends on how much your willing to spend, focuser,diag. etc.
