"Good" at sub-$100 is definitely grading on a curve, but I have the HP Stream 7 that I managed to snag on sale for around $50-ish, I think. Any VNs with really hi-res art aren't going to work because of the low screen resolution, but I've played Tsukihime, Higurashi, Steins;Gate, Grisaia, and Fate Stay Night on it and they've all run fine. Only warning is that some games or parts of games don't behave well with a touch-screen (e.g. Higurashi menus), so I have a micro-to-full USB converter and a little wireless mouse I keep around for when I need it.
I'm looking for something better when I have the cash to afford it, but for dirt cheap, it certainly works.
