Don't see why not.
I got mine in Gamestation for a tenner, rather than pay the 40 quid or whatever Amazon were charging at the time (although Amazon have cut it since, as seen in the link).
Powered, 3 ports, remote control.
I have also seen these two recommended on other forums:
4 port manual switch box for £15

3 port powered switch with remote (& built-in amp apparently) for £30
