Yep, sure am. I found some good writeups on this site.

I figure a FMU with a AFPR would be a bad idea, I can just run an SFMU in place of everything, and much simpler install. However, I can't find any used, and new one's are $350+.

Some people run something called a BEGi, but I'm not sure how well those work. I found a really cheap SFMU made by 'Spa Turbo', and a couple reviews SEEM to make it out to be a good unit, but there's too much misinformation on the internet.

I've been reading til my eyes bleed lol, can never have too much knowledge. Anyways, an adjustable FMU looks to be my best shot, but then it'll mean I'll need a wideband, which is another $160+. I used to run a wideband but I traded it for narrowband + cash on top since I was planning on selling my DSM. Oh well, plans change I guess, heh.
