I agree about Slater's.  Self quartering and nylon centers make them a must explore caster.  For me using their 7mm for S scale makes it a bit more difficult.  The hubs are really large, the wheel I was looking at, 7861, looks great however the hub would be over 2 scale ft for me.  More than twice what it should be.

Tom, it has only just dawned on me that I should mention 3D-printed wheel centres.  I have been experimenting with them for myself for quite a while,

Shapeways sintered nylon centres fitted with Protocraft P48 tyres 1.3

O-scale wheel centres printed in Shapeways Black-Strong-Flexible & fitted with Protocraft P48 tyres - scale 63" dia.

I have been pleasantly surprised by how accurate these turned out, printed with crankpin hole an'all.  The tyres must be secured with locktite or similar because any tighter fit distorts the centre.  They are accurate, the price is right, they are already insulated, they don't need painting and the slightly rough surface texture is quite like the somewhat rough finish on the real thing - sorry about the photo, it is really sharp on Flickr but something seems to have got lost in translation!
