I just got an Onda Vi40 Elite for £180 - 10" capacitive screen, A10 processor at 1GHz, 16Gb storage in-built, 1Gb memory. Same aspect ratio as an iPad, which some may not like, but it's perfect for me because I read comics off it. It's pricey for a Chinese tablet but I think they're going to become pretty popular. The ZT-282 seems to be the go to cheap tablet but there are still issues with flash on it. I had one and it's night and day compared to the Onda.
However, if all you want to do is browse websites and you're not interesting in streaming video then a cheap 7" tablet with a resistive screen is fine, though game-playing will be very restricted. For web and email only then why not?
