Vinyl

One Cut Vinyl is a print-on-demand record cutting service. Expect to pay about 20 British pounds each for a run of 10. Doesn't come with jackets.
Vinylify specializes in 10-inch (!) records. About 60 Euros a piece. But that includes a spineless jacket.

These German dudes at VinylRecorder have made a 3200 Euro vinyl record cutter. I mean. That's crazy. Brilliant. It fits on top of a Techniques 1500 turntable.
Custom Records also does one-off lathed records for $150 plus labels and jackets.
Vinylondemand does $50 12" records.
