I only paid $350 for my a Fully carved German bass, took me on my busy schedule somewhere like 6 months to repair and like another 6 months to have top shape... but now sound and worth $$$.$$
Here is the Thread: My DB project
If you live in a City with a good healthy DB market should not be hard to find ur own wreck.
Ps I don't want to pull you off your project, I just wanted to pointed out that a DB and an EUB they are not the same, and never will be. One compromise would be an acoustic EUB something with an small acoustic chamber. I still rather have the real thing, at least as my primary tool.
