Do you think it's worth the $200 Mark? I guess it's much more than $200. REX for one would need to be re-purchased wouldn't it?

You will need to check out each publisher info on what will and will not work with P3D. I've seen posts in forums mentioning the use of REX being used for real weather in P3D, so I guess it works. P3D does not use a real weather engine, so unless you use a third party addon, like REX or AS2012, you can only select the standard themes available, which are the same as the ones in FSX.

Many others are providing info on how to use different products in P3D, but I haven't found many yet. I am slowly moving many of my favourite addons over to P3D.

Only you can decide if 200 dollars is worth spending on it. I think it is. It looks very nice and I have found it to be more stable than FSX.
