I will be buying from Laminar Research. I just have not decided yet if I want to get it thru the internet or get the DVD disks. I've got x-plane 9 & 10 on DVD and I'm leaning that way for 10. Up here in Wis. we have Spectrum internet which is fast and pretty reliable. Having those material DVD's seems more permanent but I'm really open to changing. All I need is someone to convince me to go the internet download.
