Query: Cleans great, but no spareparts available

We loved how the Robo Kleen kept our pool clean. But after two years the internal gear broke. It is quite flimsy, so no surprise. I tried to locate spare parts on the internet. No luck. Called the manufacturer. They don't sell parts. They told me we could send the unit in and they would fix it. Estimated cost $140-$180. For a $3 part! A refurbished Robo Kleen is $220, so why bother!We tossed the Robo Kleen and will by a Polaris 65 or a Barracuda Zippy. At least we can get parts for these!
