I get a good price on Exide batteries at Rural King, I think you have one near Nashville. Probably around $40 or less if you have any battery to take in for a core exchange. 14L-A2 I think is the Exide replacement for your battery, much more power than that Yuasa 12.
Edit, Just checked Clymer and my bike, 14L-A2 is what you want. That Yuasa would not be a good choice.
