I'll be interested to see what the range is, and whether that price tag includes avionics, which aren't cheap. I'm seriously considering putting money away for a homebuilt, and the nearest thing I can think of is the Harmon Rocket III, which trues out at around 310 with a six-cylinder Lycoming IIRC. RVs and canards can get you and a passenger halfway across the US on a tank of gas, too. I wonder what the fuel burn is on that little jet? How much of that little airframe is full of fuel, and how much baggage can you take along?
At any rate, fully kitted out for IFR, you're looking at quite a bit more than $60,000 for a Rocket, Long-EZ or RV. New Lycomings alone go for north of $35K.
And IMO, spending big-time bucks on a VFR-only machine is foolish. Bottom line, it looks fun, but I'd want to read the POH before I jumped.
