good cheap webcam

[nullstring]

I'm looking for a good cheap webcam.
Nothing special. I don't need HD or zoom or anything fancy.

I am just replacing my old webcam from like 1998 that doesn't work with 64bit windows.

I'd prefer:

1. No more than 640x480 resolution
2. Manual focus.

Manual focus on a new webcam seems hard to find..
Considering this one right now:
