After researching the hell out of this myself... I went with a Sears
Die Hard Platinum.
I heard too many stories of inconsistency to go with a Yellow Top and just couldn't pull the trigger on it for its price and limited warranty.
I went with the Sears brand because apparently the platinum series is still made by Johnson. It's a deep cycle battery and has that glass mat technology too. But it was the 48 month free replacement and 100 month pro rated warranty that triggered my decision to buy it.
I feel like all batteries are hit or miss so the warranty was important to me.
And son of a bitch... they're on sale right now for $197. I paid $238.
