Comb the "Electrical" section of your local Goodwill. Yes, I am serious.
I don't know how they price things where you are, but at the one I go to (Goodwill Industries of the Columbia-Willamette) I often find the "Monster Cable" HDMI cords for $10-12 or so. Sometimes new in the box, even!
there "WAS" not long ago a kickass add from bestbuy selling a 40' Plenum Grade/In-Wall HDMI 1.4b Cable for 24$.
i poop you not!! a 40 FOOT HDMI cable that was Plenum Grade Shielding and even had Diodes in each end of the HDMI Jacket for Interference reduction for 24$.
my brother bought one and its a VERY NICE cable for the dirt cheap price.
