what to check for with a used sanke keg?

[seven9st_surfer]

I'm looking at getting a sanke keg off craigslist for $50 to convert into a keggle. looks ok in the pics, but is there anything in particular I should check for when I see it in person? never had one before so not really sure what to look for. Thanks

Make sure there are holes in the rim, top and bottom, or if not, you make your own, before heating the vessel.
