Go for the Tyros5! But some things to consider: Do you get the speakers too? And what about the expansion flash module? You will need that if you want to load expansion packs into your Tyros. But if you are satisfied with what sounds that are in the keyboard, you do not need it. And you do NOT need it to use styles, unless these styles come from an expansion pack. I purchased a used Tyros5 in December, and is very happy with it!
