Check ebay as well. Check the reviews. I've bought three 20ft+ cables. Ironically, the thickest one didn't work. You could also consider getting two long CAT6 cables and get Ethernet->HDMI extender like this one. It uses two Ethernet cables to create one HDMI cable. I've tested only two 16ft CAT6 cables for HDMI 1.4. I have no HDMI 2.2 sources to test with, so I don't know if it would work.
