Should I buy? Canon EF 20-35mm 3.5-4.5 USM

[camindfw]

I have found a a Canon EF 20-35mm 3.5-4.5 USM for $150.00 in near mint condition. Keep in mind that I just picked up a 28mm 2.8.

Should I buy it?

What other lens do you own...??
which camera are you going to mount it on???

If you use that focal range then sure, sounds like a pretty good deal.
