I am thinking about getting a Warmoth P Bass Body in Koa laminated to Lacewood and have them dye it in Turquoise that cost another $200 to get done. So total will be $515 just for the painted, too much?
IMO way too much for a combination like that. Lacewood is a waste if it is used as the core of the body. It has an interesting grain but you've got to see it to know. The Koa is nice but is expensive because of it's rarity, not because it's particularly pretty. Since staining isn't rocket science, you might get a nice body and stain it yourself. You'd save $$ and get some good experience in the process.
And I can see the appeal of a transparent color over a light wood like quilt maple, but why would you do that to koa?
