I guess it depends on your definition of decent money, bad ass customs cost, if you really want a one off
custom guitar it's probably going to cost you more than any factory 7 string, but then it will be built to your spec's and be exactly what you want. Customs are cool, and the truth is, a one off custom isn't really any more expensive than what some of the "high end" guitars are costing anyway, especially when you start talking PRS and the like.
