Ok I'm an old fart and lifting those vessels ain't fun. My son got me a therminator as a gift, I already have 3 vessels and want to build a brew stand to save my back! so i need pumps...the only one you hear about are marsh or chubber, i'm eyeballing this one now, but for 30$ more, here's this one... should i spend the 30$ or i there any other option that will work as fine? thx in advance..
