Very good reviews, the only downside is the lack of multitouch
But the advantage is wits frequently updates the firmware for it, so it is actually pretty fast.
Nationite MIDnite (Wits A81E) 7 Android 2.2 Tablet - A8 Cortex [MIDnite] - $199.50 : MP4 Nation!, :: Low Priced MP4, MP3 Players and the latest scoop on the newest MP4 Player
Archos 70 or 101
Not exactly the cheapest, but the design looks good.
Kickstand, thin and has camera.
Downside lack of market (can be "bypassed")
These are the few which i think is the best.
For a windows 7 tablet i recommend
Downside, generally thicker and heavier.
Note that all these have no 3G.
And of course the expensive alternative Samsung Galaxy Tab.
