Battery Recommendations

[EdHale]

I just realized that my '06 LBZ was 4 years old this past weekend and I'm still running the original OEM batteries. They seem fine, but obviously they are getting older.
What seems to be the battery of choice now days? When I had my 6.5 Suburban I used Optima Red Top batteries and they were great although a bit pricey.
Any current thoughts for when the time comes?
Thanks guys.

optimas are still great batteries though u are right a bit pricey. i usually run the best napa has to offer,and have had no prob getting 5 years out of them.

I used to swear by Optimas until they got crappy with warranty work.
