there's alot of dealers selling on ebay now,and if you know who they are why buy on ebay,go direct,because its always going to be cheeper !,selling on ebay as a dealer incures costs,which increases the price.just as an example i bought a pair if a10 cylinder sleeves recently listed on ebay at £60 plus postage,pressed the contact details of the seller and purchased them direct including potage for £50.
if its second hand then you've got to pay whatever,but if its new then go to a dealer direct.
