Absolutely - Azed and Everyman in the Observer are online, the ST's Mephisto, their regular cryptic and the cluewriting comp are in the paper. Have you tried the monthly Guardian Genius yet (also online)? And there's always the Guardian's daily (non-prize) cryptic, and a new Private Eye at the end of the week. Stacks to have a go at, even if you don't want to buy a paper or pay an on-line sub.
