I purchased 2 computers from Jetline systems for my life size 777 cockpit. From the very first phone call with Ken and Greg its has been nothing but ongoing support for the last year and a half. Not only are they professional and good at what they do, they are also good friends and always willing to help you with whatever you need. If you are new to the sim world and need honest and proper guidance, look no further then jetline systems...they are simply the best!! thanks Greg and Ken!!
