From a strictly inches-to-dollars ratio, the 25-inch HannsG HZ251HPB is a great deal.

It's not everyday you're able to purchase a 25-inch monitor for $170. Most monitor manufacturers are able to stay in business because of this fact, but for a couple days a year, some are willing to throw you a bone.

Newegg has started their Black Friday deals early by discounting several electronics products from the computer vendor's stock, including (so far) four computer monitors:

Unfortunately, I've not reviewed any of the aforementioned offerings, so I can't attest to their quality' however, if you're looking for monitor deals this weekend, this seems like a good place to start. The sale ends on Sunday, 11/28. Happy hunting and good luck!
