Now you're looking to start a fight. Aero Fly Pro and Aero Fly Pro Deluxe are available from [link=http://www.aeroflypro.com]AeroFLyPro website[/link] www.aeroflypro.com. The other sims are Reflex, and RealFlight G3. I'm not sure where to get Reflex, but you can get RealFlight G3 from Tower Hobbies, or your LHS may have it in stock.

I have AeroFly Pro and love it. It has since been replace with the Deluxe edition which I believe improved the graphics and the physics. I have also flown on RealFlight G2 but I really didn't care for the respone feel of the simulator. I think that all the simulators allow for you to plug your radio directly into the computer via a cable that should be supplied with the program. You may need an adaptor for your radio.

Aero Fly Pro and Aero Fly Pro Deluxe originate from Germany, and RealFlight is produced by Great Planes.

RealFlight is going for 249.96 USD in the current Tower Hobbies catalog. AeroFly Pro is still available from their website for 99.95 USD, and the Deluxe edition (which I would recommend you get) is going for 179.95 USD. Now, RealFlight is going to come with its own controller, which will make setup a little easier. But I like that fact that I had to use my own radio with AeroFly because I got comfortable with it faster. Which ever you choose is going to help you either way.

I would do a little research on both and then make a decision based on what fits your needs.
