just a heads up on the roller coaster ride.
when you are contemplating buying you will have moments when the factors pointing to a successful purchase all seem to click together and provide a state of euphoria that the purchase will be the best you can imagine.
then some doubt will creep in. you will start to feel some doubt and eventually convince yourself that the idea is the worst thing that you could have ever contemplated.
then you'll realise that you are being somewhat pessimistic and you will start to re-evaluate the purchase with some optimism.
when you are in the middle of this it will be quite an emotional roller coaster ride as you alternate between doubt and confidence.
take your time.
there will always be another aircraft that comes available if you miss out on this current one.
the only consolation I can give you is that your second and third aeroplanes will involve less of a roller coaster ride.
