I have always heard nothing but good things about Kenne Bell chargers, which is what I was originally going to go with. However, the dealership I work at is an authorized Saleen (S7) dealership, so I get a pretty healthy discount on all parts (including chargers). Is one stronger/more reliable than the other? I would love to take advantage of the discount, but if the Bell is going to last longer it might be worth the extra money. What do ya'll think?
