What are the disadvantages to buying used simulator, other than the obvious, "might not work right"?. Can models still be added, and can upgrades be added if offered?

I bought a used g3 from Ebay and was able to register it with great planes. They just wanted proof of purchase. i keep mine updated and now have the g3.5 beta version. I also have about 100 planes.

You should have no problems at all.. I have APF and it has been running for like 2 years... I just upgraded to FSOne! It's nice but you better have a NICE and NEW computer!!

Terry,
Only thing to watch out for are unscrupulous E-Bayers selling the disc without the hardware (dongle). With G3 and AFPD that cable with the dongle or the controller, if it is the version that includes a controller is the "key" to running the software, the software disk by itself is worthless, the vendor won't replace "lost" cables.
Good luck,
Pete

P.S. I may be puting my AFPD for sale after I have a chance to see FS one

Terry,

I've got RealFlight G2 that I'll sell. All of the G2 addons work fine for adding planes. The G3 expansion packs do not. I'll let it go because I use G3 almost exclusively now.

PM is you are interested.
