The right BL ESC to get for this would be?

[A RC Dude]

Ok, for future porjest sililar to my boat, i would like to use something other than my e-maxx system so i can still run my e-maxx. I was thinking, i already have a 9XL motor and heatsink, so now, all i need is a good ESC that'll work with it. All I need is a good ESC that is cheap, can run with the 9xl, and 5s LiPo. other than that, i don't need anything fancy. what would be your sujestion?

Thanks for the help!
