A G1 is a beautiful aircraft. However for you to consider that for your Algiers-Spain commute shows me that you don't really have a clue what it takes to operate one. For the hourly cost of a G1, you can run 5 King airs simultanuously. Yes they may be cheap to buy but they cost more to operate an hour then most jets do.
Please do yourself a favor and get some professional advise if you are serious about this, just looking at pretty pictures in Controller is not going to get you the aircraft you need.
