Prebuy A&P IA in Wisconsin/Minnesota area

[Medicpilot]

Looking for someone to prebuy a M20J in central Wisconsin area.  Someone familiar with them.  I am more concerned with airframe issues than engine/prop issues.

I imagine that many would recommend Oasis Aero, formerly Willmar Air Service, in Willmar, MN.  They are a Mooney Service Center and have been in the Mooney business a long time.

2nd on Eric in Willmar. Busy but very knowledgeable.

I have heard nothing but praise for Jason at Jed-Aire, KBBB, Benson, MN. From multiple sources, though I have not personally worked with them. But I would probably prefer them over Oasis, if only because I think Oasis is overbooked and may be overlooking stuff in the rush to get everything done.
