Steve The price of (4) layer boards has changed very little in the last 5 years. As off-shore vendors got into the (4) layer market, the pricing became very competitive. Your greatest advantage today, relative to pricing, is how bad does the vendor need the work? This has the greatest effect on the pricing. Be aware, the industry is beginning to get very busy. This will effect the future pricing of any layer count in the future. Sorry, can't offer anything further on this subject at this time. Norm Einarson <[log in to unmask]
