There are some great Boeing models by PMDG.  Their website is http://www.precisionmanuals.com/. ; The 737 and 747 are great.  They are on the pricy side, but are worth it.  There is also Overland (http://www.overland.co.jp/english/sms/index.html). ; They have the 777-300, A300-600R, A32X series, A330, A340, and A380.  They also have a good MD-11.  I hope this helps.
