Bit of an old thread, but I thought I'd add my list. In order:
C-172
Beech Sierra (flew ok, but best glide was 105 MPH...that's not a glide, IMO)
Citabria
Piper Seminole
C-150
172RG
J3, PA18, PA12, and J5 Cubs, modified to one extent or another for banner towing
Oh, and I safety piloted for a guy in an amphib C206 with a G1000 in it. Flew like a dump truck with all that float on it. That G1000 has more bells and whistles than I can count though.
That's it for now, hoping to expand my list as time goes on.
Edit: forgot about the 150, slow but fun
