There was a file I PM'ed you a file last year which had: Name, Manufacturer, price, Cruise Speed, Max speed, Range, Useful load and Take off Distance for 86 types.
Personally I would also like to see MTOW, Fuel Capacity, empty weight.
The world directory of leisure aviation here includes:
Empty weight, MTOW, Vs0 Vcruise & engine.
Any combination of the above would be great, I'f you can import from a spreadsheet Im happy enough to consolidate one entry from the two sources.
