I sold my first few for barely more than the parts. I feel more secure and capable now, so I've started raising my prices to actually make it worth my time, at least some of my time. Still, I think I'm pretty cheap, as I start out at around $1,000 and go up depending on the specs. But I don't have an established reputation, so of course I'm not going to charge a premium price.
Also I have a day job - so I'm not trying to put food on the table with guitars. Just more tools in the workshop.
