As Whirly says there is all manner of PPL equipment and study material on eBay.
I would come at it from another angle though - rather than buy a complete package and then eventually sell off all the bits you don't need or like on eBay, buy the stuff second-hand on eBay in the first place.
There are always a few Thom books, kneeboards, CRP-1's for sale.
Thom books that are an edition or two out of date often go for very little, but (with the exception of the Air Law where you need a fairly current JAR updated book) the content is no different.
