I'm a fairly new convert to the DTKG crossword but have been doing the Mail on Sunday one for years - in fact I only buy the paper for the crossword. I haven't won yet and my husband frequently points out that I have spent far more on the papers and stamps than the prize money is worth. I like the challenge though, and you never know when you might need those little snippets that you pick up from doing a GK crossword. Book tokens would be appropriate prizes - I've spend a small fortune on reference books which I use for solving the crosswords. I have a set routine 1)brain, 2) books, 3) internet!
