Tim,
I love my PM2000. It is a great saw. But if I were to do it again I might get a Grizzly as they are lower in cost and some have more features.
I do love love love the built in casters. It helps when I was in a small shop to be able to move it around to cut the pieces I needed to. But I think there are a few Grizzly's with casters as well. And with the extra savings, I would surely get another tool.

PS I got mine in 2008 for $2100 and that was with a 10% discount. I think the saw is now closer to $3000 at least for the work bench with vise style.
