Does anyone type full words anymore? N E 1 dun ths b 4 drives me insane. Maybe I'm just getting old. Anyway, if you already have an Optima is one thing, but I wouldn't buy a new one. I haven't had good luck with those batteries in over 6 years. Deka batteries are pretty good. You can get some rebadges for the $150 range. I really like the Diehard Platinums. They aren't cheap by any means, but they have the thickest mat than anyone else.
