FYI, the rebate notice has been removed from the listing after KitchenAid verified that this model is NOT eligible for the rebate. The Amazon reviews for this model are pretty bad, listing several problems including motor burnout. I was in the market for one but I'm going to wait until Costco has it back in stock at a very similar price as if there are any roblems I won't have any hassles returning it.
Edit: Lots of confusion on te Amazon page for this deal but the consensus seems to be that KitchenAid will honor the rebate. It seems that the model number listed is by Amazon is incorrect but one customer was told that the box it comes in will have the correct rebate-eligible model #. It also does have the metal gearbox so should be fairly durable.
