I'd actually like to go a step further and design my own PCBs for these kinds of projects, but the hard part is finding good schematics to work from, and the right parts for my Eagle Library.
I find that most of the expense in these DIY mic pre's are the inflation of the kits and the costs of the PCBs. It's the same with the stuff from BYOC. We all know we can do our own PCBs and source our own parts and build the exact same kit the way we want to for much less than the cost of the kit from BYOC, but for someone beginning who has no idea how to do all that a BYOC kit is money in the bank! I always recommend nervous beginners to try that out before learning to source their own parts. It's way easier that way. But, when you get into doing this, I can build stuff that they charge 100 bucks for, for a mere 25 or 30 bucks before my labour - and most of that is hardware, not the PCB or electronics.
