Query: Great until the error codes started showing up!

I have owned my Canon Pixma MP830 for two years now. Worked AMAZING! Until the error codes showed up, first there was 6A00 which in NOT in the book under problem solving error codes. Then error code 5100 started showing up. I called tech support who were great, except could not help me. They said the problem is in the circuit board and I could either buy a new one at their discount (they gave me a code that is good for two weeks) or pay to get it fixed and I would have to pay for the estimate to see what that would cost. SO my dilemma .... buy it again... or get something else. Lemon or Cherry... roll of the dice. But buying a new one every two years is not what I want to do!
