Some of Richard's products are only available from him, I think. You might get the occasional copy turning up in the UK second hand, but don't forget it's actually called Journey into Hypnotism when searching.
I agree with Mark - Richard's produced some amazing ideas (although I haven't bought his most recent DVD yet, due to a slight concern that there's a lot of reheated material). The best things he's produced, in my opinion, are his various books. Even if you never use any of the tricks, he has some truly interesting thoughts about performing.
