Not downloadable unless you subscribe, Farrwest, but:
The Listener in Saturday's Times. (used to available in the Times Crossword Club for £25 a year, but they've pulled theplug on that and you've got to subscribe to the whole paper)
Enigmatic Variations in the Sunday telegraph (On-line sub to Telegraph puzzles about £30 a year - so cheap).
Both themed like the Spectator and the occasional Azed.
