I was looking at them yesterday as I need to top up my glass beads too. The steel shot ones sound good and at £22 for 10kg it only £2 cheaper than the 5kg I was going to get from Tinks (it also means that I can get another kit instead)

It says they are 2mm in size so that makes them half the size of my spacer beads so they are roughly the size of the poly pellets, if thats of any help to anyone.
