I've used Leapers in the past...and at the sub-$100 price range, they're a bargain. Once you start blowing $300+ for the SWAT models, and I think there's other scopes that are much much better.
Personally, for performance and value, it's hard to beat my Nikon. I also just ordered a Pentax from Ebay from one of the few sellers that will ship to Canada...I paid $99 for it (3-9x40), and I think that will be a great value also.
