I've got one of these, bought it about 5 years ago.
Good machine, very well made and powerful.
As it's a rotatry you'll need to be very careful with it as it will burn through your paint if used incorrectly, unlike a dual action polisher.
Worth buying an old panel to practice on before you attack your own pride and joy though. When I got mine I bought an old Audi 80 with very faded (alpine white) paint and it brought it up like new.
