Looking for used Eppendorf Centrifuge 5810R or similar in Canada

Hello, We are a not-for-profit school in Calgary, Aberta, Canada. We purchased a used Eppendorf Centrifuge 5810R which turned out to be a dud (the infamous "error 17", likely requiring a new PCB). We are looking to buy a new used/refurbished centrifuge for our school lab. Ideally it would be Eppendorf 5810R or similar. What is a reliable and affordable source? Thanks!
