I agree with the poster that said cheap is not good when considering dust collection. How much is your helath worth?
I'm looking at a Grizzly G0548 2HP DC with 1 micron filter and 1,700 CFM. Cost is $475 + $74 shipping. A little more expensive than the other setups mentioned above but comes with 1 micron so no need to retrofit, and at 1,700 CFM is more powerfull than the above mentioned solutions.

I started with absolutely nothing. Now, thanks to years of hard work, careful planning, and perseverance, I find I still have most of it left.
