Where to find decent castor wheels

[Now Playing]

Was at Builders Whorehouse yesterday looking for decent castor wheels and no surprises their range is limited and generally nasty (albeit not cheap). Any ideas where I could find a decent variety of quality (steel) castors. Looking for wheels that have around 70mm diameter and 80x80 or smaller baseplate.
