Are there any services that are easy to use and cheap that will print and bind a pdf for you? I'd love to get spiral-bound programming books or textbooks that actually stay open on a desk without having to pin them or destroy the spines.

Although that's probably breaking copyright laws...

  cheap that will print and bind a pdf for you

Google for thesis / dissertation printing. There's an entire industry dedicated to printing and binding one or two copies of PDFs :)

I'm pretty sure copies for personal use are allowed explicitly by Fair Use laws. As long as you aren't giving it away or selling it, I think it's acceptable.

...if you're in the US. Unfortunately most countries do not have the idea of fair use.

lulu is pretty cheap, although the wirebound options are pretty limited.

I've had Fedex Office do this for me before.
