That my be a tough one, unless you find a used one for a deal, their pretty pricey. Morebeer has one online, but it's not shipping until July "ish". I'd keep an eye on Probrewer.com in the forums and you could get lucky. Here's the link for the Morebeer one just in case: http://morebeerpro.com/products/pump-centrifugalstainless.html
