So much can go wrong--some pieces I've had have been trouble free for years.---Some not so---. I figgure it had a problem and was cared for.--EVERYTIME I see this 'checkup' thing;I assume it went in for any other reason than just a checkup.But, hey I'm a suspicious kinda guy.---Oh, the guys that didn't send their piece in for a 'checkup'---They end up in the "disputes" colum.--'ya think?
