It's seems when I look into rotaries the good ones cost bank ... major coin .. I know zip about them ... tried one in a shop for a minute or two .. and that one cost 3 g's So anybody have some knowledge and experience with them .. I can't imagine every kid in Europe plays a three thousand dollar trumpet nor can I imagine they all play junk. A kid here in the states can find a really decent piston trumpet anywhere from $100 ( okay if they find a real deal) on up. Second question ... what is the deal with them ... sound and playability wise.
