I bought a Pentax 80ED (used) on ebay, and a Manfrotto/Bogen tripod and head (used) also on ebay a couple summers ago. Once the dust settled I had about $1000 CAD into the setup. The review at the link Mebiuspower provided is pretty accurate.
I've been pretty happy with the Konus Konuspot that I bought about 6 years ago, but if I was buying today I'd consider this system.

Pentax 80ED with 20-60x eye piece seems to be the benchmark spotting scope, even when comparing to Sworvski.
