You can DIY one cheaper, of course, but you're still looking at a few grand. If you don't mind slightly less accuracy, and want to do it as a kit (instead of completely homebrew - which can be a pain to learn about if you aren't familiar with CNC already) - this company is pretty well known:
Also something else to keep in mind: If you do metal work, you can purchase (or build) a CNC plasma cutter. You typically have to supply your own plasma cutter, or spend extra for it (what you normally pay for is the table, mechanicals, and interface electronics - computer is also extra). Many or most of these can be easily converted to adding a router for woodwork (provided it has a height control head to handle it). Just make sure you get one that can handle 4x8 sheets.
There are also CNC routers, etc that can handle much smaller sizes, if you aren't going to do anything big. Many of these are easy to DIY and there are plenty of examples, tutorials, books, PDFs, instructables, etc - on how to build one.
A small desktop CNC router can be homebrewed for less than $500.00 (plus a fair amount of time). Of course, you will need to have access to at least some basic tools to build one, and be competent at using them.
