Jay,
I reckon you could print out CAT3Cs comprehensive post and use it as your shopping list – although it will add up to a bit more than the weekly food shop, especially if you go for the Oxford CDs!
In addition to above list take a look at this thread:
PPL Equipment
It covers everything from types of pens right through to sunglasses. The general consensus was that it is better, in the long run, to buy bits and pieces individually rather than go for an all in one pack.
Also check out ebay there is usually loads of PPL stuff up for grabs.
Have fun!
