For a higher power scope the swaro ATM/STM 65 20-60 for ultralight the the 50mm scope with around 30x. I have the minox md50 and for what it is and price it has been great, probably the best bang for buck. I think I'm going to upgrade to the vortex razor 50 just because I can get a super deal on one right now. The Nikon 50mm is also pretty popular.
