Dusty,
As I'm sure others will point out, a good bit depends on how you intend to use it. The types you listed (generally speaking) are good for one machine (at a time) and the runs between machines and DC should be kept as short as possible. I have a friend who has a Grizzly 2 hp model and based on how his works and my own requirements, I have ordered theirs (model G1029). Can't really say exactly how it will go in my shop (hoping it will really suck though ;). If you like I'll be glad to keep you updated. The specs were what sold me. About 1550 CFM and a static pressure of 12.3. (Also they were giving away a good bit of free stuff and it was on sale...delivered it's only about $100 more than what you're looking at). At any rate, it's worth a look.
It does require a 220v service but that's not too much of a problem for me. On the whole, I tend to go for the "bigger is better" line when purchasing shop equipment. YMMV....usually disclaimers apply.
Peace.... Spencer Ten Mile, TN
