I have a Lanes Loader for 410, and Lee Loaders for 12 gauge. It works okay, if you only want to load a box or two at a time. If you want to load any quantity, get a Mec. There's no comparison. The crimps weren't great, but I picked up a 410 crimp tool on eBay, and the crimps are much better.
If you use and like Lee Loaders or Lyman 310 tools, you'll dig these. If you want actual production, these aren't for you.
