Call Scott Smith at Skysmith Insurance. 1-800-743-1439. He shops all the markets and is very good with Experimentals. He has written over 15 policies for me and is very sharp. He also sells the Smith Miniplane homebuilt plans. I know he writes a 4P-Turbine with a Garrett down in Texas. I was surprised It was $8000 less than the 4P-Turbine with a Walter that I was flying and was insured with another broker at the time.
I have used Nationair in the past for 4 or 5 policies but I really like the professionalism and prompt service I receive with Scott.
Scott also does forums at Oshkosh and Sun-N-Fun. He is one of the go to guys in the industry.
