I think most of them are made by the same companys, just with different labels on them. I would just go to wal-mart or K-mart and get one, this way, you can get a replacement under warrenty almost anywhere you are at. Sears batteries are overpriced, avoid them. I have also had a few people recommend "Interstate" brand, if you can find one.
The best is the Gel battery if you want to spend some dollars, cant think of the name right now, but they are around $150.00
