Thanks to Garry's recommendation, I am now the proud owner of an Odyssey PC1200MJT battery for my TJ. Batteryweb.com was the best, beginning with their friendly phone service to their follow-up email to their quick delivery.
I placed the order around noon PDT to BW.com (3 EDT) on Tuesday and it showed up to my office by noon Thursday. This was standard ground delivery too (battery drop-shipped from Phoenix). I will definitely buy from them again and recommend them to others as well.
