On descent near flight idle fuel burn can get down i= nto the low 20's.=20 As an example, I have flown nonstop from Key West to Huntington, WV with a h= eadwind in 3:30 using all of my 112 gallons in the wings but still leaving m= e 34 gallons in my belly tank. This averages out to 32 gph.=20 On multiple flights I have estimated that I have right around 4:30 of flight= time until dry starting with full fuel ( though I generally use my belly ta= nk as my full hour of reserves and never get close to dry). I have 146 usab= le gallons.

Recently there was a Lancair 4= Turbine for sale at $250,000; it sold 

and now is back for on t= he market at $299,000

http://w= ww.globalair.com/aircraft_for_sale/Experimental_Kit_Aircraft/Lancair/PropJet= __4_for_sale_68010.html

the biggest shortcoming is that it has on= ly 125 gallons of fuel.  figure 50 gallons the first hour and 35 gallon= s the second hour. that leaves you just over an hour fuel if you land at the= two hour point. 
you say an hour fuel is excessive to land with, su= pposing that brings you to 10,000 feet, then your "cruise" hour of fuel is o= nly 40 minutes.

but, hey you can climb at 4,000 feet a minute.
