I just picked up two of these 4K players from a local Wal-Mart for $25.00 each! (One of each model.) Another local Wal-Mart that had them in stock was selling them for $49.00 which is still a decent deal compared to the $109.00 MSRP on BrickSeek. There appear to be two Sanyo models that Wal-mart is selling. They seem to be the same from what I can tell. This doesn't have any smart features or high-end audio, but if you do your streaming from an external source anyway, this is a great deal on a basic 4K player.

Another site I found said these are manufactured by Funai and sold at Wal-Mart as Sanyo, but as Phillips and Magnavox at other stores like this one at Best Buy. (Not sure if this is an exact match, but it looks very similar.
