I've been running one for about six months now, loading 9mm, .45 and .223. If you're a turret guy, you'll like it. After fighting a loadmaster for a year I sold it and got the breech lock pro. One of the things I don't like about true progressive presses is the lack of tactile feel when seating primers. On this you will load and seat the primer just like you do on the turret. Also, if something gets out of sync when running (like an upside down case) it's not a major undertaking to correct it and get back to running. If you are loading multiple calibers it is more expensive to set up for each one - about $25 vs. a $12 turret. I bought the bullet feeder but still haven't been able to get it to work right. Don't waste your money on it.
No, it's not a Dillon or LNL, and it's not intended to be. I will say that you will get more out of this press than a 550, IMHO (and yes, I've owned one). When it's all set up it takes me an average of 18 minutes to load 100 rounds, loading the bullets by hand, going at a comfortable steady pace. That is more than adequate for my needs and over 50% faster than my turret with the auto ejector.
Hope this helps.
