Their are a few folks in the area. I at the moment cannot remember his name off the top of my head but he dives what he calls the Kevorkian. A odd looking home built unit. It was popular quite a few years ago but now with the commercial units available it is not so popular to build your own.

Functionally, it's not a hard thing to do. As Greg points out, with the plethora of off-the-shelf units at reasonable prices these days, though, you won't save any money whatsoever building it.
There's a really cool woman in the USVI that built her own CCR setpoint controller and has posted a few times on SB. I've been meaning to try that one myself, one of these days, but it's low on the priority list of things in my build queue. Building an eCCR is a fascinating project as there's a lot of room in control theory, algorithms, power consumption, etc, to play around in virgin territory. Building an mCCR is just figuring out how to trickle oxygen into a breathing loop at the right rate.
If you're just looking to experiment, an old Drager Dolphin converts to an mCCR very nicely, with about $150 worth of McMaster parts, a couple of spare Apeks DS4 regs, plus the need to add some kind of monitoring. They come up for sale all the time in the $800-$1500 range, depending on condition and accessories. Before the KISS and the rEvo knocked some amount of off-the-shelf affordability into the CCR market, converting them was a very popular option. See http://www.tecme.de for fancy solutions and spares.
