the wood will generaly run u about 100$, 10$ for fret wire, 10$ for pots, and 5$ for the output, after that, it all depends on ur tastes, u can spend 100$ more.... or grab a set of used 7 string pickups for about 10$ a peice of ebay if ur not to picky, bridge probably about 30$ u might want to get that new, and tuners, 20$ (if u shop around), nut 3$?, and what ever u want to spend on paints..... so ur looking at around 200$ base price.
