IMHO the Cloud9 portover with the wonderful mods by Henk wins hands down until the release of the milviz offering.
It is 50% freeware, meaning that you have 7 minutes trial time after which the gauges will stop working and will stop the model from being used. But using the mods by Henk will end the trial period and you'll have a working Phantom in FSX for all eternity.
I bought mine during the FS9 days and so nothing stops me from using the original models and textures in FSX.
Also, the modelling is just exquisite! It is unbelievable that this model was developped for FS9 when you fly it in FSX. I mean, there are several native FSX models (payware) that don't even come close modelling wise.
And with the mods by Henk, it has turned my FSX into a Phantom simulator. No other model gets the mileage that the Phantom gets.
In fact, I'm going to fly it right now!
