This puzzle is notoriously difficult. I've messed around with it a bit, but I think it'll be one of those puzzles I keep in a solved state and then whip out when people ask what the most difficult puzzle I have is. Turing is okay. It's got that old school Calvin puzzle feel, which isn't necessarily a good thing.
It's a 15 year old puzzle, so keep your expectations in check on the packaging and turning quality. I'm not a fan of the blue color, but I'm happy to have this in the collection before inventory runs out.
