In need of an HDMI Switcher... any suggestions?

My current home theatre setup consists of a 1080p PlasmaTV with a sole HDMI port occupied by my HD cable box, a PS3 slim, and an Apple TV on the way.

Looking to amazon.ca, I found an abundance of switchers at a variety of price points ranging from single to triple digit price tags.

Unable to recognize most brands, surprised by the generally contrasting user reviews, and overwhelmed by the significant price range, impulsively ordering a switcher did not seem like a balanced decision.

So, does anyone know of a 3+ port HDMI switcher, that is reliable, compatible (with a PS3 and Apple TV), reasonably priced, and available in Canada?

Thanks!
