I think for basic orders Warmoth are better priced. But, when you start adding options their price starts scaling alot faster than usacg and can possibly end up costing more.
The Warmoth neck was $419, where as the very similar usacg neck was $480.
But when you consider what I got for the extra $61 - 1/4 sawn maple, graphite rods, rolled fingerboard, to specify the wood grain, choose either nitro or poly finish, half the build time and faster shipping it doesn't seem like a big deal. I'd have ordered those options from Warmoth too if I could.
Warmoth charge for daft things like $15 for no butt holes and $35 for a straight radius + different back shapes at $35 :? :?
I don't have a problem ordering unseen A) because of the reputation and B) because they go through every detail with you like a trainspotter. When I ordered the neck I specifically asked them to find me the most boring and straightest grained maple with as little grain run out as possible... and it was no big deal. But with Warmoth, what you get is luck of the draw unless you go showcase.
