Well I bought the 6600GT card and installed it in my computer. And after almost clicking on the "purchase" button for all three sims and not being able to make up my mind, this afternoon I purchased G3 on ebay. I went with it because I'm going to be flying alot of helis and for ease of use. I really wanted XTR but would have had to make an adapter for my Multiplex TX and just wanted something I could plug in and go. They all look good, I like the indoor stuff on AFPD best. It's hard to decide because they all seem to be good, it would be an easy decision if one of them is a piece of junk or way better than the others, but that doesn't seem to be the case. The good thing is if you buy a sim and don't like it you can always turn around and sell it on ebay for about what you paid for it, as long as a new version hasn't come out. Thanks for all the input and opinions.
