Here is my UDS. The barrel is a bit wrinkled, and the lid is a little large, but it seals fine. Have some pork smoking in it right now :)
The basket was made at my neighbors welding shop. The handles are a rake handle I cut into three pieces.
On my test fire, it held 230 for 6 hours. I went to bed then, so it probably kept it there a few hours longer. The temp management is much better than my cheap upright.
