I hate to say it, but anything DIY'ed generally has a much lower value than any name brand. I'll never get back what I paid for parts and time in building various gear through here, and in kits.
But I also would never have gotten the joy of learning and building stuff myself. So DIY provides an education and an outlet, but not necessarily a good ROI.
Would your customer understand, "hey I used a special star ground scheme on this unit so it's really quiet, and high quality FM caps and, and, ..."
Nope. They'll ask, "does it work?"
And if it does, they will still see it as a home-made affair.
That said, my best investments have been in DIY because I love doing projects.
My best financial investments have been in name-brand gear like Neuman mics, Avalon preamp. I plan on getting some decent monitors later this year or next, and treating my room...after I get a room
