Has anyone ever bought a truss rod off eBay?

I know I can just buy parts off of stew mac but eBay is cheaper and I would only want to buy from stew mac if I were getting all of the neck parts at once to avoid paying shipping fees multiple times.
I don't want to ruin all my hard work buy installing a cheap truss rod that doesn't work.

The ones I was looking at are these:

17-18" is what I would want for a 24 fret guitar, right?

Also, does anyone know of a shop in the Los Angeles area that would sell lutherie supplies?

Cool, I just ordered a 18 1/8" truss rod. If they are good enough for explorerbuilder than they are good enough for me. I actually based my headstock design off of a blackmachine headstock and your zebra wood explorer.
