I've built 4 of them..just for reference...it's usually in the $12-1400 with pickups/hardware etc..for doing it up nice. I usually pay my local tech at the music store to wire and set it up though..so could possibly save 1-200 if you do those things yourself, or even more if you can do the finishing as well. Warmoth does a good job on finishes though. I can agree the fretwork is usually not perfect, but as noted earlier in the thread they are good out of the box.
I have bought a couple body blanks off Ebay and had a buddy with a CNC router cut out my own designs and used Warmoth necks. Both were learning experiences for me..the finishes were a motherfucker as something in the grain fill did not agree with the top coats..but still turned out ok.
