Thanks for all the replies. I have Skyview and an SL30 now, and am slightly leaning towards adding just the 400W. The 400W will mean a lot less wiring and should fit the budget better.
The extra COM would be nice, but there are a lot of options incl. Dynon's own integarted COM radio.
The backup NAV would be nice, but then again i may only use VORs less than 2% of the time. The SL30 would be sufficient.
I had thought up the VOR to GPS scenario, but again, only using VORs less than 2% of the time and the rest GPS makes that point obsolete.
I am getting closer. I was considering everything from an old GX-50 to 480 to 400W's on up. It gets frustrating and confusing trying to sort through these options while still on a budget.
