What battery to use?

You might also check out Napa. I got one of their top-of-line 72 month batteries for my daughters car when it was in Chicago. A month after we moved to FL, the battery went dead. The battery at the time was actually only about 18 months old. I took it back to Napa and because it was into the pro-rated part of the warranty, a brand new replacement battery cost me $18. The fact that a cell went out in the battery itself was not a real good indication of the quality of the battery, but that could also happen to any battery. The plus side is that because it was a top-of-the-line battery, the warranty in this case was more than worth the extra cost of the battery. A cheap battery would have mean't paying full price for a brand new one. They were great about the replacement too. No questions, issues, comments or fighting to get a replacement. Even with the original purchase in Chicago and the replacement in FL. I would definitely go back there again after that.
