Welcome Tom i have also fount the shop on Catawiki (www.catawiki.com) to be quite reasoably priced, i have bought quite a few now from there that i had on my wish list with no complaits yet, the only bit of advise is check the image you are viewing is the actual stamp you will recieve, if it is a scan of the actual stamp it normally has an icon saying the image has been uploaded by the seller Steve
