UPDATE:

The two-for-one deal is no longer on Costco.com but my two local Costco B&M's have two 46" Aquos choices. They have the Sharp Aquos LC-C4655U and the Sharp Aquos LC-C46D64U both for $999.99 after $300 off. The latter is the one that was offered on the two-for-one deal but it's even better now because you don't have to buy two and you can save on the $100 shipping costs.

I was scouring the Internet to find the differences between these two models, of course wanting to get the better one if there was a better one. The best I can tell, the D64U is the better model. It is still listed on Sharp's site for whatever that's worth. It has 1 less HDMI input but it has a jack pack on the side for the convenience of hooking up a camcorder or other temporary input. It has more powerful speakers (15W vs. 10W) and perhaps more importantly, has a 4ms response time vs. 6ms. Both are full 1080p 60Hz sets. We bought the D64U tonight.

The funny thing is that the C55U was selling better at the two stores and we think that the main reason is that the box it comes in is covered in colorful graphics whereas the D64U came in a pretty plain brown box. I think that it's actually an older model than the D64U.

If anyone can clear this up beyond what I stated feel free. I am pretty sure I made the right choice but wouldn't mind confirmation.
