I would expect about 10 years but this is like a car lasting ten years, you have to take care of it and it doesn't mean parts won't need replacing now and again. I wasn't aware of any price gouging, I saw some around Christmas on eBay but is this a recent problem? I can promise you this if you place an order with one of our dealers in the next month or two you will get it at the current price even if they put it on backorder.
