Archos is selling their 10" tablet for $270. The 7" is $240. I've used one of the 10" models and found it fine for web browsing. Sadly, their new models coming out in September are said to cost $300 and $370.
Looking back, I think the original price was $299. I hadn't realized it earlier, but Archos also has a low-end series that runs from $99 to $199. I doubt the hardware is very good in that price range.
