Hey Drew, a few guy here have had luck with keeping an eye on craigslist. I've seen some real steals so if you can use a cooler for now and can take your time looking you might find a great deal.
I don't know if this is close to you and might be a bit out of price range, but there are some out there, this was right on the first page of results.
