im running one and have loaded around 8-10k rounds on it. No problems at all. I have been good to go. If your looking for an entry level progressive the Pro 1000 does just fine. You will hear people say "Dillon is better" or "RCBS is better" and they may well be....but they sure should be for costing 3x as much and doing the exact same thing.
I have used the Lee 1000, now have a Lee loadmaster. For the few extra bucks get the Loadmaster. Great press, 25k and going strong.
There is a learning curve but once you get in tuned in it runs like a sewing machine. If you need any help feel free to PM me. Good luck.
