I ran a Viggen FMIC for a while. It worked GREAT with my 14b sm16g and e3 16g. Once i went to a bigger turbo and started running 22psi daily, it didn't cut the mustard anymore.
$50 is a VERY good price for the fmic. They're not so easy to find anymore. If i recall, i paid $150 for mine, back before the influx of bar/plate ebay cores for less money.
