Ask HN: Where can I find decent near-eye displays for less than $200?

Hey folks! It's my first time here, so take it easy. I'm looking for a near-eye display for a little wearables project. I'd prefer a fairly compact form-factor. I'm planning on only rigging it for one eye. Bent-prism looks especially cool, but I'll take what I can get. I'm not afraid of popping apart cases if that's what I need to do, but I'd like to keep soldering to a minimum. I've got a shoestring college student budget, so cheap is good.

Thanks in advance!
