If you don't have FS9, then definitely wait.
The FSX version is still at least a couple more months away* so it comes down to whether or not you want to wait. If you get the FS9 version now, there will be a discount (significant discount) when you order the FSX version. So its not a waste of money.
And personally, I think the $45 is very reasonable. In fact, its almost stealing. The aircraft IS the most realistic and in depth simulation of a military fighter available for MSFS (But be forewarned, this does mean you will be spending hours on hours studying the flight manual....). The flight model is a fully simulated FBW system that performs nearly identically to the official F/A-18E performance specs/ratings released by the US NAVY. And as far as the systems go, if its not simulated, its probably classified. If FS addons were supermodels, this would be Heidi Klum.
...and other companies (not to name names here...) is willing to charge that same price for a "OK" model with virtually no realism.
Go over to the website
www.vrsimulations.com and the forum and have a look. If you like military fighters, this is as good as it gets, and the FSX version will be even better.
