I don't know about Van's specifically, but it doesn't apear there will be any major price increases in the avionics world. I know the MD series of indicators are going up slightly, but other than that I haven't heard of any other increases for the year (radios, GPSes, EFISes, A/P's, etc..).
I wish we could say the same about Aerosport Power and Classic Aero.. Both of them look to have raised pricing significantly in the last 2 months.. Just in time to break my bank.... ;-)
