N-Strike Elite Stryfe is certainly making the rounds. From being spotted on Toys R Us shelves around the United States to now getting listed on Wal Mart's website, the Stryfe will likely be a hot item this holiday season.
I picked mine up at a local Toys R Us, though there's always that higher markup you'll get buying them from there. Keep your eyes peeled and post a comment if you've found the Stryfe near you!
