Post-renovation kitchen cabinet?

[DTisme]

We're looking for a kitchen sink cabinet and since i'm going to paint it anyway, I don't want to waste $ on a new one. (But I do want one that's not falling apart!) We've tried Smith's, the liquidation place on Kilauea, the Habitat for Humanity store, and of course the Kea'au recycling center. I've also been checking Craigslist for weeks, but nothing there. These things seem like they're everywhere when you don't want one! Anyone have any ideas? Mahalo!
