Harbor Freight - free shipping. Drill presses from huge to gargantuan. Good quality for home use.
Big Lots - had 8" benchtop for $39.00, same import as sold by Harbor Freight.
Amazon.com - free shipping. Delta, Jet.
Homier - Your traveling tool seller. They often have some good deals on returned/refurbished power tools.
I have a Delta 12" benchtop drill press purchased from Lowes about 8 years ago. Not a minutes trouble, made to last. Paid about $139 and will probably have it for the rest of my life, be that long or short time.
Grizzly - Yep, good stuff. But a drill press is a drill press. If their price with shipping is close to other sources, you will have a good tool. I own some griz stuff and like it. Easy to shop with them online. Lots of drill presses from itty bitty to Whoa! Momma!!
Disclaimer - No, I don't work for any of these guys, but they've all managed to get some of my money.
Also check your local flea markets. You can often find some good stuff at a reasonable price. Ask the seller to run the press and let you check the runout.
