I bought this a couple weeks ago, and it ran great out of the box. Get help to put the head on, as it is very, very heavy. I also had the experience others are having with the belt cover having shipping damage. Grizzly is great about returns, and they definitely don't give any hassle. With the belt cover damage, the idler pulley shaft was bent, and they replaced that too, and threw in a couple belts and shipped overnight!
Regarding the removal of the spindle pulley to remove the belt cover, don't get a puller. Make some light taps with a rubber mallet against the side of the pulley toward the base of the shaft, perpendicular to the shaft axis, while turning the pulley so you have taps all around the axis. *Light* taps will knock it loose, and it will pull straight out without effort.
I hope they figure out something different for shipping the drill press head to better protect the belt drive cover. This seems to be a consistent issue with shipment for other folks.
Oh, and if you're oscillating between the bench or the floor model, the only difference is the column, so if you think you need to switch later, you can just buy the column. The head is the same.
