I bought a Mini 18 40 watt machine a little over 3 years ago. I've had to replace 2 tubes which were under warranty. Huge hassle and downtime, but at least it didn't cost an arm and a leg. In April this year the machine stopped working AGAIN and Epilog said it needs a new tube. $1,400 cost, because the warranty ended. I couldn't justify paying that + shipping and customs fees ( I'm in the Philippines ) and kinda gave up on it. Got tired of looking at it sitting there and emailed Epilog and expressed my unhappiness with having to replace 3 tubes in 3 years after all of the great reviews I read about their machines. Was totally shocked when they replied and said they would replace it for free!!! That saves me $1,400 so I'm a "happy" camper. Hopefully it will last a long time.....
