What's a good replacement battery?

Well my E30 would wait until my 335 goes into the body shop to start acting up...smh

Anyway, my battery seems to be dead. I went to Advanced and they want $110 for a battery! What's a good replacement battery that I can use that can fit the battery location in the E30?

Optima yellow top or interstate batteries are great

Thanks for the advice. I'll see if I can find a yellow top.
