Don't be swayed by a cheap price on crimp connectors. A good quality crimp terminal will be made of tin plated copper, not aluminum. As I mentioned above FTZ, Burndy, T&B, AMP, Molex etc. all make good quality insulated and heat shrink crimp terminals, so you don't necessarily need to buy them at West Marine.
As an example, I buy 100 FTZ Crimp'N Seal adhesive lined yellow ring terminals from my distributor for about $70.00 per 100 so my guess is that you should be able to find them for less or slightly more. West Marine sells 25 Ancor terminals for about $32.00, or about $128.00 per 100.
