help with eheim pump

[niloc16]

ok so i have tried J&L , aquatic addictions, and some store in calgary. i have also tried to size up other needle wheel impellers to work with no bloody luck. can ANYONE tell me where the heck to go to get another impeller. seems like no one is carrying the H&S line either anymore to get an impeller from them. i have tried to contact H&S and Eheim for advice with no response. nice customer service, hey!
