One more opinion - I recently purchased the 80mm Kowa 824 with the zoom and couldn't be happier. I also checked out the Swarovski and the Leica, also both 80mm models, but wasn't fortunate enough to be able to do it side by side. My overall impression, though, was that all three were great scopes. I don't think you can go wrong with any of them. One further note - I have compared the 80mm scope to my old 60mm, side by side, in low light conditions, and the difference is very significant. If you plan to do much birding in the early morning or evening I'd sure go for one the bigger scopes in spite of the increased weight and bulk. Good luck, and great birding!
