Lava Guava. Definitely.

Why? It has a very low sun cost, and a mediocre recharge. Second, its lava pool is seriously damaging, and when it's erupting, zombies on nearby lanes get damaged, too. Trust me. Save your gems for Lava Guava, and you will seriously NOT regret it. It's perfect for dealing with large groups of zombies. And if a zombie is frozen or stunned, the Lava Guava won't erupt until the zombie starts moving it again, making it possible for other zombies to come and get burned, too.
