Time to upgrade my watercooling rig and I need a new pump. I need one that has 1/2" ID barbs and costs $40 or less (preferably less). I've been looking at the Hydor L20, Via Aqua 1300, Eheim 1048, MaxiJet Inline 300GPH Pump, and one of the Pondmaster pumps. My question is, which one is the best for that price range?
