I have and use both, as well as a Loadmaster and 40 year old turret press and Classic Cast single stage.
The 1000 is for. 38 Special and .357, Magnum, the Loadmaster does my .40, and I now do 9mm on the 6000.
I don't have a bullet feeder on it. My set up is size and deprime in station one, Lyman M neck expander in station two, powder drop in station three, powder cop die in station four, seat in station five and crimp in station six. I have only loaded about 3000 rounds on it so far. I find I am slower with it than the Loadmaster. There is an extra station to keep an eye on as you go. I kinked the spring on the primer system shortly after I got it, so now I have a few spares on hand. I'm still not sure how that happened. Slow and smooth is what I found works best. This winter I sat down and did two batches of my 9mm loads. First one was 600 rounds, then came back and did another 700. Total time was about 2 and a half hours. Maybe a little more. One issue I want to address on mine is that the mechanism for shaking the primer tray doesn't work very well, so I have to manually give the tray a flick to make sure the primers slide down into the feed chute to keep it full.
My 1000 works well (it has loaded A LOT of revolver ammo), but the three extra stations on the 6000 sure are nice.
If you want the bullet feeder you can eliminate the powder check die, or the neck expander.
Also, the 6000 has a different footprint than the other four presses, so I had to drill new mounting holes in my bench for it.
