Does anyone bother buying second hand ones or are they all new. Anyway - old school Propex on ebay (X1 model) , not mine I hasten to add. I do have one of these and they are pretty bulletproof. This anes 100 sheets at the moment. http://www.ebay.co.uk/itm/PROPEX-HE...ervan_Caravan_Accessories&hash=item461b39051a
