Avionics start to take shape

My avionics are starting to take shape.  After going to Oshkosh this year, I have a much better idea what I want.  I will go with a Dynon Skyview (10″).  I just bought a fancy Narco AT-165 transponder on ebay for a great price, as well as a Garmin SL-40 from the same guy.  I’ll be looking for another SL-40, or if I can find a good deal on an SL-30, I’ll take it.  I need to keep an eye out for an audio panel, altitude encoder and vacuum attitude indicator (in case electrics go down).
