Check out www.swfa.com and www.natchezss.com for really good prices and selections of scopes.

Here are a couple very inexpensive scopes:

BSA .22 Special 3-9x32 Riflescope with Rings Clampack = $24.86

BSA 4x32 .22 Special Series Scope with Rings = $17.99

I myself have this one: BSA Sweet .22 3-9x40 for $40

I find that it is sharp edge-to-edge, holds a zero well on a .22, and is bright. It also has an adjustable objective lens for very accurate short distance shooting (25yards and under).
