I've been bitten by the payware bug again, and I'm glad! Just purchased the Shockwave "Wings of Power" Messerschmitt BF-109 E3/E4 package.
By far the most realistic FS aircraft I have ever flown - truly amazing planes!
Hope my shots do it justice, the level of detail and realism of these 109's are astounding.
For FS9 and FSX - get it here ... http://www.shockwaveproductions.com/store/solo/bf109/
And at less than $20.00 US it is an incredible deal.
