It depends on whether you plan to run it as a portable unit, or if you want to add some duct work, and what kind of equipment you have. A drum sander requires much more suction than a jointer. Duct work for an 800sq.ft. shop requires more oomph than for a 400sq.ft. shop
For the money, you can't beat the HF / Wynn filter combo - $300 to go. That's what I have. I ran my first board through my planer, saw the chips come out, and bought this thing the next day. I added the filter later. It's nice when you can do upgrades in stages. It gets most of the chips and dust, but I'm still doing some cleanup with the shop vac afterwards.
For $500, you can have the Grizzly G0548 delivered, but it requires 220V. It has a canister, with flapper cleaner. Real 2HP, not Harbor Freight 2HP.
The Delta is a decent unit, it has a little more power than the HF. But, I don't like bags. They get dirty real quick, restricting airflow. You can wash them, but it's not pleasant and what are you going to do while it's drying? A canister is the way to go. Adding a canister to the Delta brings you close in price to the Grizzly or JET.
Oh, and you're going to want to get a remote. Those are $40 - $50. You can delay the purchase, but eventually, you're going to want one
