I'm definitely one of the "$199.99 or bust" people, but it's still a pretty good price all things considered. I'm pretty sure it would be inferior to a full fledged monitor from a decent manufacturer at the same price, but the 3D capabilities, 240hz refresh, and extra goodies make it a pretty decent option.
Just remember that if you want to take advantage of the 3D capabilities, it only supports two modes from what I understand: 720p/1280x720 at 60hz, and 1080p/1920x1080 at 24hz. For games, you'll basically be restricted to 720p at max, and of course you'll lose out on some brightness from the passive glasses. 3D movies should look nice at 1080p though. Also, if you want to use the 3D feature on a PC, you'll need the appropriate 3D support from your videocard manufacturer; Nvidia I know charges an extra fee to allow output to 3DTV formats, not entirely sure what ATI has for 3DTV support. Although, some games and even Youtube allows for SBS 3D if you don't mind losing the extra resolution.
Edit: Huh, sounds like you can use a custom INF file with an Nvidia card to get it to natively support the display for Nvidia 3DTV Play according to one of the reviews on the Best Buy page, that might make it a bit more appealing for some. Also for those interested, Motorstorm Apocolypse currently trades in for $13 credit at Best Buy, which if you include the 50% bonus going on and a 10% Gamer Club Unlocked subscription, brings it up to just over $20 back if you trade in the game.
