I have one. Works pretty well, it is just a single stage and functionally there is very little difference between it and my MEC 600 Jr. There is the very practical difference though, that the DL155 has been discontinued for years and Hornady's supply of parts is quite depleted. The one I bought had several severely worn hinge pins and would have been next to useless if Hornady hadn't still had some spares. That was more than 10 years ago, they may not have any currently. The MEC 600 is still in production and spares are a snap.
