Allwinshop via eBay offers this 3-Port HDMI Switch for $2.45 with free shipping. That's tied with our mention from two weeks ago as the lowest total price we've seen for a 3-port HDMI switch. (Outside of other eBay sellers, it's a current price low by $2.) This switch supports 1080p video and features three HDMI inputs and one HDMI output.
Note: This item ships from Hong Kong and may take between three to nine weeks for delivery.
