Modern Art online retailers?

[chim]

I have a couple of bare walls and I want to put up some cheap art to liven up the space a little. I love the whole murakami/superflat movement, and am looking for just cool vibrant art in that vein. I was wondering if you guys knew of any websites that had prints similar to this? Hopefully more budget oriented, because I dont have 2 grand to drop on a murakami print.

That's probably the funniest piece of art I've ever seen

I know this is obvious, but you can find some on eBay from other kaikai artists - I picked up a Takano Aya print a few years ago, but it's just sitting around in my room and hasn't been framed yet.
