It looks to me like the Archos 70 and the Archos 101 (shipping in October) are the best of the upcoming ipad rivals. These should be available at Amazon.com. I would trust them (they have a great return policy) over taking my chances ordering something from China.
The 10.1 has a capacitive touchscreen, Android 2.2, great audio/video support, hdmi out, accelerometer, 8 gb onboard storage, 3d acceleration, and expandable memory (micro sd). It is also thin, and lighter than an ipad. For $300 it has everything that I've been looking for. The only downside is that it doesn't ship with the google apps or official market (it uses appslib instead), but those are usually easily hacked (see Pandigital Novel, Augen Gentouch, Archos 5, and Archos 7HT) in after release.
The 7 inch version (the 70, not the 7HT) is the same as the above and comes in at $275.
