RE: buying new sim, maybe
I have seen comments that Phoenix sucks for planes, but the heli guys love it. I have had AFPD and Aerofly 5, but have gone back to FS One since they released a new vesion improved for 3D. If realistic flight physics is of great value to you for 3D and advanced aerobatics, check out FS One v2. If you want a lot of video game bling, then that is a different story.
