Thanks Doober, really appreciate the reply but sadly they don't ship to the UK. It did however confirm that the smaller bearings could be 5mm and i'd found them for a reasonable price on ebay.co.uk. And it also made me remember to look on ebay.com rather then than the UK site and i've found some for around $4 each which isn't too bad, certainly a lot better than the local sellers as they want at least $10 each.
