I second the recommendation for Aerotronics in Billings.  I used them and they did a fabulous job.  Timely, within budget, very responsive, very knowledgeable.

Dico,

I can tell your friend of one shop to stay away from in Florida.  I made a package deal with Sarasota Avionics for everything on my panel.  VERY BAD EXPERIENCE from start to finish. 

I have heard a lot of good things about Aerotronics in Billings, MT.  They do a lot of work for experimentals and do custom built panels for customer installation.
