I think Dayvo covered the essentials.
Of course, for some, basic recreation is always going to be more expensive than for others, it depends how you like to relax. And even within one hobby there are vast differences - we see that in cycling. I seem to remember the survey said a bike was an essential - anyone know what monetary value they gave a bike? I suspect there are some on here who wouldn't think it was worthwhile if it cost less than £500, and some who get about perfectly well on something worth £50...
