I know 24 Gold is the one the scent hounds love, but I really like this one too. Currently £10 at The Fragrance Shop http://www.thefragranceshop.co.uk/products/24-24-the-fragrance-eau-de-toilette-50ml-spray-15628.aspx
10% off (2 or more) would take it down to £6.75.
The fragrance encompasses lavender, lemon, mandarin and bergamot in top notes, with a heart of nutmeg, cinnamon, pink pepper, mint, annis and cumin, while a base incorporates amber, musk, oak moss, vanilla and woody notes.
Its flacon is masculine, with number 24 in the central part of the glass body, with clear lines, with a heavy, metal stopper.
It was launched in June 2009, first marketed exclusively in the Middle East, then progressively in the rest of the world throughout 2010.

(he can be a little sweary)
Incredible longevity, apparently.
