need new battery, i checked schucks and its at like 27 pounds or so for my 94 civic coupe. i checked out those hawker/ odyssey batteries which are like 1/2 the size and 13 pounds or so. where can i buy it cheap either online or in a store? ebay is like 85 shipped for odyssey.

my coupe is a dx, only running a cd player and sometimes fog lights when its rainning. no sub system, no a/c, power steering, so i guess it should be alright. i hope my alarm wont drain it overnight. has anyone used these batteries and have cranking problems with it? thanks
