I think you are all comparing apples to oranges. A No 12 Griswold on eBay consistently sells between $150 and $200. You're essentially looking at something handmade in the Finex. It appears his marketing strategy is not to get picked up in the Wal-Marts but in the high end cooking boutiques you see. A brand new All-Clad skillet of the same size is in that price point. Looks like a pretty innovative design and the handle is really appealing. Also has a pretty cool looking logo. Let's face it, the logo is what makes a Griswold large block worth more than the small block. The quality of each is pretty darn equal from what I've seen and in many respects the quality control of the small block is better.
I'd give it a shot, though I wish he would offer non seasoned pieces, maybe at a reduced price point. Also from a marketing standpoint he needs to come out with a smaller #6 or #5 skillet, something that can be easily handled with one hand by a woman. My wife loves the 5 and 6 Wagner's but she won't really touch the bigger ones as they're just too heavy.
