It's worth mentioning to anyone that may be interested in these to also check out Lee Krasnow's site for some of these and the other bits that he currently has available.
That said, even though his craftsmanship it awesome I still feel that he prices his puzzles too high. Although I imagine that if he does this as his main source of income rather than a hobby then it can probably be justified.

Here's a vid of 7 wood I picked up from Lee after our get together recently (sorry it's a bit blurred!) and after that is a video of the meeting held in London with Lee and Eric.
