Whoever told you that 4K is something for rich people, that it was still out of reach for average Joe, couldn't be more wrong. I just stumbled on the (new) prices on the Seiki 39 inch and Seiki 50 inch 4K UltraHD televisions on Amazon, and was pretty amazed.
UPDATE - There's now also a 55" version of the Seiki TV, going for $791 on Amazon.com
If you're up for it - hit up the links to Amazon. I personally don't think these super-deals will last terribly long!
