Now that seems to be settled...SHIT POST TIME!!!Awesome advices from everyone, I understand there is no "perfect" ship that would do everything perfectly (especially at low cost) and that we are still in early Alpha so a lot of ships and functions will change. Didn't really think of that before, maybe because I never had the Aurora changed since I got her.
My "vision" of the citizen I would like to be in this universe is not just a fighter, or a solo trader, I would like to do some trade, try to mine a bit, go out simply exploring, be part of a wing of fighters (have to get some friends ingame, my RL friends aren't really into PC gamming), be part of a crew manning a turret, etc, its the many possibilities that got me into it in the first place. Jack of all trades untill I find the one/two most awesome for me ingame, and stick with them choosing my ship(s) accordingly.
I know we will be able to buy ships with ingame currency but if a ship (and not even one of the more expensive ones) costs 100€ on the store I can only wonder how much grinding is needed ingame to get it... and I believe other ships won't simply be attainable by one player, as it should be, but thats another topic.
For now, as advised I may stick to my Aurora and try to find more people on the PU to fly with, and when I feel the time to change is here I will probably start with small upgrades (and small cost to wallet as someone pointed wisely), so getting ships that can do trade and somewhat defend themselves like Aurora->Avenger->Cutlass->... And preventing myself for regreting and even be mad at the game as pointed.
So I guess the natural change of starter ship may be for the Avenger, thanks again for the advice everyone!
