I would also take into consideration the amount you were given for your trade in. Some stores are more generous with that than others. My dealer doesn't even take trade ins.
Also consider that you got rid of a machine that you no longer wanted without having to sell it yourself and got a new machine at a price that you were comfortable paying. Hopefully you also now have a good dealer that you can feel comfortable asking questions and maybe getting some extra lessons from.
Enjoy your new machine.
