Well... black or blue does not matter for me but the price tag from shop to shop is not the same and it turns out that there is one with a blue box that is a bit cheaper than the others. If in doubt I would rather pay a few tens bucks more to be sure to get a Q900 but if all are equal I'd rather save these 10's bucks. Hence my question.
