WAT?  I've seen '59's go for upwards of $120,000 in good condition. And  you want a 76? Unless you mean Deluxe, (mid-72 to early 76) a custom from that era is certainly not as good as a mid-50's or early 70's. I personally would want a '61 LP special. Less than 400 made with P-90's and the SG body. They sound amazing.
