The SVR80 roughly is $120 (dont have exact price in front of me at this time)plus shipping (its a beast, about 50+ pounds) You may want to look into the Interstate Spiracell battery (made by Optima for Interstate) I think I can get those a bit cheaper, but I think one of the major part stores had it for $129 (would be close to same with shipping) Also ebay always has yellow/red tops up for around $105.
