I decided to go with a Sherline mostly due to space problems. For a small shop, it is very nice to be able to store the lathe on a shelf. This lathe is plenty big enough to make most of the parts needed for locks and triggers. As has been mentioned to do barrel work you need a much larger lathe. If I had more room I would get a larger lathe but at least I do have a lathe.
Also, when I was looking around I was looking very hard at the lathe that is sold by Micromark. It is a chinese lathe but has the longest bed of all the micro lathes out there.
