Barnes and Noble is offering the Nook Color on their official ebay page at $200 through a coupon on the top of the page. Even at $250, the Nook Color is a solid tablet with lots of potential once rooted or after a ROM install. Also, it's the only tablet as far as I know that boots straight off the micro SD slot, so you can run a ROM off it and use the rest of the space for apps and storage, letting you play to your heart's content without breaking the warranty. I've had the Nook Color for about two months now and I'm quite happy with the early Honeycomb build and eagerly expecting full Honeycomb now that the Xoom system dump is out and AOSP is around the corner. You can read my reviews here and here and there's more info past the break.
As I've said before, the Nook Color is solidly built, packs good specs and the option to boot off micro SD and the active developer community make this the most solid 7" tablet that's out. The Honeycomb SDK came out last week, the AOSP should be dropping within a few weeks and we already know it's able to run Honeycomb quite impressively given the constraints of a hacked up build from the preview.
You should still look into the Eee Pad Memo and the HTC Flyer just so you know what's out there, but they won't be matching the $200 price anytime soon. If the Nook Color caught your eye, keep in mind that B&N only ships to US addresses and there isn't any word on the return policy (I bought my first unit from BestBuy and the screen wasn't glued on properly making the bottom of the screen unresponsive at times so I returned it - but nobody else seems to have had problems).

UPDATE: some users report calling B&N and the return period is 14 days, unlike in-store where it's 30 days. B&N physical store will also not match the price, since it's an ebay exclusive.
