Thanks for the answer Andrew. I too am after a touring aircraft and consider a transponder, GPS, at least 1 strobe and decent fuel capacity a necessity.
I guess I am spoilt by my Skylark that has transponder, Avmap GPS, full light package ( was actually built for night VFR ), a ballistic rescue chute and an in-flight adjustable prop but comes in with an empty weight of 321kg. At 600kg MTOW this allows full fuel ( 90 litres = 63kg ), 20kg of baggage and still leaves a very realistic figure of 196kg for pilot & passenger. About the only thing I would change would be to loose some people weight in exchange for another 10-20 litres of fuel. Oh, and I still want to do 115 knots. Looks like replacing the Skylark is not going to be easy.
