I went ahead, and ordered this one, just a few minutes ago. It came with a $40.00 off coupon. I think it may have a little better stabilization than the Wolfang GA300, but the main difference that I am paying $30.00 more for it over the 300 is that it's waterproof without a case, and evidently has a more durable construction. I was going to wait for black Friday sales, but I went ahead, and got it over with. I hope to be able to get it mounted on a helmet, so it basically sees what I see.
