Looking for a category-targeting ad widget

Hey all,

I'm trying to find an ad widget that does the following:

• 125x125 squares
• click tracking
• automatic expiry
• determines ad displayed by category

I've found two so far, which if I could heat up and meld together would be perfect:

WP125 (tracks clicks and expires ads, but doesn't target by cat)
Ad Squares Widget (allows targeting by cat, but it's all manual entry, and no frills)

I'd be happy to use Widget Logic to target by category, but, of course, WP125 doesn't let you keep multiple lists.

Any ideas? Thanks!
