New Battery, Which one should I buy?

I have a 99 cavalier 2.2. The battery has had it. What is the best one to buy that will fit easily? I looked at the optima site but doesn't look like they have one that will fit. Also I live in Canada so my selection may be limited.

Thanks in advance

optima all the way... yes they do fit.

Thanks!

Bought an optima Red Top $150 at Costco. It was the exact same size as the OEM. 5 Min Job to switch out. Why doesn't anyone have that one listed to fit for our 99 2.2 cav? It was a perfect fit! Is it hard on the alternator? WTF!

Anyway thanks for your response.
