I just bought mine from Mazdatrix, I think it was like $91. Not real cheap, but worth the $.

teamfc3s.org has a DIY sections where you can make your own. You do need some knowledge with electronics though. It cost me like ten bucks to make mine. I haven't used it yet, but according to my multimeter it works.

I'm not great with electronics, and mine worked the first time. I only had to make one adj. to bring the clamping V down a tad and it's been in there for a year and a half w/o trouble so far.



If you do get an RB one you might want to adjust it's clamping voltage also (if poss., I would assume you could). I've heard it clamps @ 3.3 or so and mine as well as several other people are using around 3.6.



I'm sure you've heard the following: Be careful with higher-than-stock boost levels.
