cheap but good quality HDMI source splitter?

[Sensai]

The Sceptre 42 LCD from Costco has only 1 HDMI from the specs... is there simple splitter available for more than one source? Does the tv upconvert?

Will plan to have the cable box, samsung 1080p upconvert dvd player, self built HTPC, onkyo 780/790 system all setup together.
