Piglet released an outstanding Zlin-50 that's free. You can find it in all the usual places.
For payware, the IRIS Christian Eagle is great, but you might get infuriated by the horribly looped sound package. It sounds like someone is beating the heck out of a tambourine while in the cockpit at full throttle. Other than that it's flight dynamics are very good and it looks good. Maybe someone from IRIS can confirm whether it's fixed or not.
