[sdiy] Advice for selling gear: FCC part 15 certification?

[Bret Truchan]

Hello again!

You all rule!  Thanks for being so friendly!

Eric, of Metasonix, was kind enough to warn me that, if I ever want to sell 
my creations legally, I'll need FCC part 15 certification.  I was wondering 
if anyone has any more inforamation about going through the certification 
process.  It looks expensive!!  If I'm probably going to sell less than 50 
units, and they don't cost much,  how can I break even?

One piece of music gear that I'm thinking of making uses a microcontroller 
-- and that's about it.  If the microcontroller already has passed FCC 
approval, do I also need to have my unit approved?  If my gear is entirely 
composed of off-the-shelf components, do I still need certification?

Thanks a ton for any advice!
- Bret
