You may get a cheaper battery but this is a investment that you don't want to keep making over and over. Buy a good one right off the bat and have no worries. I know first hand how great there customer support is and that means alot when you have a problem or question. You can jump on the web site and talk to a "real person" and get answers to your questions instantly. Ok, I am a little bias because I drive for them but I'll tell you one thing, as hard as money is to come by these days I wouldn't tell you to spend the extra money if it wasn't worth it but in this case it is.
