A local battery store has the following. The Northstar seems like a good price. I thought Northstar batteries were the same or more than an Odyssey.
I can get an East Penn AGM at NAPA for around $220 when they have a 20% off sale.
Precision brand #27-AGM $219.88 with $24.00 Core
NorthStar brand #NSB-AGM27 $289.95 with $26.00 Core
Lifeline brand #GPL-27T $319.95 with $26.00 Core
Discover brand #EV27A-A $340.71 with $19.00 Core
Odyssey brand #ODX-AGM27M $396.99 with $26.00 Core
