I have been the owner of a computer cable business for thirty years and the qualities one needs are; expertise and good personal customer service. Jetline has both. I don't have to tell you how frustrating it is when you fowl your flight simulator up with some new tweek or program which won't load. I just did that and my Learjet locked up before I got to the runway. A friend of mine recommended Jetline to me. I sent an email explaining my problem and Greg sent back a simple message asking if I could explain a bit more on what I did he would help. I called the service department and got Ken, who took over my machine and fixed it within minutes. I offered to pay and he said no. The following week I called back with another problem, and again Ken fixed it and again I offered to pay and he said no. I wanted to make this short. The bottom line is if you have any reservations about buying one of the great machines offered here, I assure you your Jetline experience will be a good one. Again expertise about how computers work with flight sim to provide the best possible performance and knowledgeable personal service. Jetline has both!
