Thanks for that link mate,
No I'm not going for the Sampler, but the one I read about was ordered configured in C Orchestra tuning, C top, C# bottom. A sneaky way to get a cheaper Saxony (sort of).
After some serious research, I'm going for the Saxony. It has a different slide and comb to the Sampler and is more air tight too apparently. As a long term investment, the price difference is not a lot really.
