Kobelco SK115SR Water pump

Looking for a bit of info, my 115 (ser #yy03-05227) needed new belts which I just installed, in doing that I noticed that the fan was a bit "wiggly" so I believe it's time to replace the water pump, it is not leaking but I don't need it to launch itself through the radiator when it finally has had enough. It has the Isuzu BB-4BG1T engine. I called the Kobelco dealer and they quoted me $900.00, they said this was cheap, it used to be $1400.00. My question, is there anywhere else someone knows...
