Wondering what everyone recommended as far as heaters

Setting up 55 gal with a sump

Currently have a Steal Pro that came with some used equipment I bought, with a BOX so I will be returning to Pet Smart today.
(I really liked the design on the stealth pro, but I did have one fail on my freshwater tank back in February)

This is a 200W, thinking should move up to 250 - 300W.

Pet Smart carries Fluval anyone using that??
