I've decided to buy a Tuxing dual piston compressor - will be getting it from Amazon mainly due to their return policy. The Asurion 4 year protection plan is offered with this compressor - 4 years (really an extra 3 years) for about $135. I don't generally like or buy extended warranties or "protection plans" but having two Yong Hengs I know compressors like this are prone to needing parts and service down the road. Do any of you have experience with this protection plan from Amazon?
