I ended up choosing B&B's HR22 AGM batteries, they seem to be top of the line when it comes to SLA AGM batteries and they use high quality virgin lead. www.zbattery.com has the best prices on B&B batteries that I could find anywhere. Also, don't be tricked by the batteries on batteryspace.com, they look like B&B's on the site, but they are actually much lower quality Tysonic copies. They are only about $10 cheaper for a much lower quality battery.
