Mark:
Yogi Berra would probably say that "75 percent of your starting problems are half electrical", and the battery cables are a big part of this statistic (sic). Have a look at FCP Groton for reasonable pricing on these articles - benefits being: OEM parts fit better, warranties on the products, fast delivery service, and the like. This is one area where I'd be inclined not to attempt to economize TOO much, and I've seen a few instances over the years where a fault in a battery cable was extremely well hidden. BTW, I have no affiliation with Groton or any other of the reputable suppliers out there, but take a minute for a quick search on the 'board and I think you'll find out that this is probably the best way to go.
Hope this helps,
Garth.
