Yes.. I'm aware of repaints at both those sites.. particularly the second which actually states they're for the FS9 model patched to FSX.. a number of which I have I do like the FS9 'patched' model but couldn't see the point in throwing more at the WoP3 version 'for the hell of it'.. hence me dipping my proverbial toe into WBS. Flight models can be down to personal preference (regardless of how accurate they're reported to be) and overall.. I don't find one markedly better or worse than the other.. they both have certain strengths and weaknesses. One area that is more easily measured is actual model accuracy and here, there is no comparison. WBS models are not generic.. they're reproductions of the aircraft depicted
So.. the rest is down to personal preference

You won't be unhappy with the FS9 Mustang Tom and there are loads of paints for it Not sure what $19.99USD works out at these days but it's not a bad price The patches to make it FSX native are still available at A2A so should you move up in future, you can take the Mustang with you
Your right Dave just got it only flew it for 5 minutes and I love it only comes with one aircraft but I will repaint it anyone know if theres a paint Big Beautifle Doll for it. Plus is it suppose to come with a 2D panel cause all im getting is a green panel along the bottom of my screen with some gauges.
It's been a very long time since I've flown it in FS9 but I can't recall there being a 2D panel.. just 2D windows that open up various panels. There's a picture of it wearing the Big Beautiful Doll scheme so you can guarantee there's one for it. Have a look on the A2A forums (http://a2asimulations.com/forum/index.php) under 'for 2004' and you'll find the WoP2 Mustang support thread. They usually show what paints have been done along with links to them. Some of the threads can be a bit 'testing' but they're worth a read
Try Simouthouse, Avsim, Flightsim.com and OzX for repaints noting you want them for the WoP2 FS9 model only. The maps changed with the FSX upgrade and changed yet again with the WoP3 release so neither of these will fit the FS9 model.

TBH.. I'm more than a little confused with the A2A site. As far as I can see, there is only one P51D advertised for FS9 and that is the D/H pack. The price is indicated as $19.99 but when you click on 'details' it opens up another page with a more expensive price The D/H pack shows only one repaint for each so if you bought it from A2A's site.. you have the D/H. If you bought it from elsewhere, I really couldn't say. From what I can see.. some of their older titles (Shockwave releases) are no longer sold
