Online machining

I stumbled upon this nifty little site that supposedly allows you to design your own custom machined parts using a CAD program that they provide. Sounds like a good idea to me, especially if you're buying in bulk, it looks like they have some good deals. I have no idea what quality their work is, but it's worth looking into if you need a custom part. However, this definately requires some CAD ability. Check it, play around with the program.
