Well I tried out the Wilco FeelThere 737-300 yestarday and was very impressed. I usually fly the PMDG737 but I thought this one had a more accurate real world systems layout. The sounds are pretty good with it. General framerates are better then the PMDG. Other then it acting a little wacky with a VNAV climb it works perfectly. I do think in the next update the VNAV climb profile as well as autothrottle will be fixed. Has FMC or can be flown with FSNav I have heard.
Here is a link to more info:
