Off the top of my head:

http://www.axiotron.com/index.php?id=modbook if you want to pretend that Apple makes tablets.

http://www.alwaysinnovating.com/ smaller screen and thicker chassis but longer battery life for $300.

Various Windows laptops, harder to find since noone wanted to pay the premium for a touchscreen.

If you want a browser-only tablet, install Chrome OS or something.

$200 still is in the land of magic ponies and unicorns though.
