I got given one of these presses awhile back with a bunch of different dies. Used it recently to knock up some 357's cos I was doing a one off load and didn't want to adjust my progressive press. The dies weren't labelled and I had no instructions but found some on the net, once I'd sorted that out I found this to be one of the most consistent and easy reloading setups I've ever used.
The biggest downsides are the oddball die size and it's inability to FLS. I'm going to keep using this press for straight wall cases that I only need small volume of. If you're only doing rifle calibres or need to FLS every time I'd go for a traditional O frame press though.
