I'm in agreement with you, Anax, even though I'm coming at it 'the other way round'.
I often look at crossword books in shops but I'm only interested in non-cryptic ones. I instantly reject anything which also includes cryptic crosswords. (I also reject well over 95% of the books of non-cryptic crosswords because they're all far too easy. Trying to find non-cryptic crosswords which are still a bit of challenge, akin to the Saturday Times 2 Jumbo clues, is like looking for hen's teeth!)
