Best pump for easy set pool?

[Mrsdion]

I have an above ground polygroup Summer's wave 18"x4' easy set up, the pump has broke after a couple months of use. We called and got a new piece. And it's broke again. Me and my husband are first time pool owners and we are trying to figure out what the best pump is to buy. We so not want to purchase the same type of pump it came with but have no clue what we are looking for. Any advice would be greatly appreciated

I have the Intex sand filter 70110 and my pool is about the same size. I like that I'm not changing filters every other day. Also the pump has enough suction to operate my Hayward Aquacritter.
