i used the washable medela from babyshop with my 2 kids and where so handful and useful, comes in a yellow box, were to me even better than the disposable
I tried Boots and Philliphs Advent washable breast pads and both of them leaked so I had to come back to disposable. From the disposable beast pads only Mothercare brand, the ones in the dark pink box with aloe vera, are up to my standards. I think I have tried all the pads in the market and only the Mothercare ones are good.
did you check in Mothercare (the one with maternity section) or Destination Maternity? I had a set, but can't remember where exactly I bought them from. Actually I never liked them as they were quite uncomfortable and thick comparing to thin one time use pads from Mothercare.
