Look at the link. There's a shipping charge, looks like $69. But there's no tax though if you're not in MO, PA, or WA. If you are in one of those states, just drive there. So it might cost you an extra $50 or so to go with the grizzly. I haven't looked at the specs for the delta you mentioned, but I bet the griz is better.
The shipping is handled by a freight company. They show up with a big truck. It's not quite as automatic as ups or fedex, but it's easy. You might have to pay a little extra for lift gate service, sometimes not. It depends on the freight company. You can also usually pick it up at the freight terminal to avoid that problem.
Grizzly has been around for 20 years or so and has a good reputation for customer service. Just do a google search for grizzly here or on woodnet. I wouldn't worry too much about parts. Things like motors, knives, belts, pullies, and bearings are sort of generic, so you can get them anywhere if something happens to griz. I doubt that though. These are also generic chaiwanese machines. Chances are high that someone like sunhill, wilke, shopfox, or even jet or delta will have the exact same machine painted a different color and priced differently. Griz seems to be doing great and is putting pressure on all the others at the moment.
