I bought one of Cobalt 60 's Lee Pro 1000 and what everyone says is spot on....once you get familiar with it, it runs pretty good. It didn't take me too long to get it running good but I'm not using the priming system or the bullet feeder. I am using the case feeder which is nice.
Cobalt - do you use the bullet feeder? I haven't tried to get that running yet.
I used it for a while, but was not crazy about it. My main complaint was that it made it difficult to visually check the case for powder level. Every once in a while it would drop a bullet as well. It is fast, but I decided it was maybe a bit too fast.
