I have not tried this switcher but am curious also. The review from C-Net seemed to be favorable and I generally trust their reviews.
I need an HDMI switch as well and this one sounds good. The Geffen is way too expensive and the no-name switches I have seen on E-Bay cost as much or more than this one.
If you get one post how you like it. If I get one sooner I will post. Good luck.
