Sterling Silver Chains

Hi

I am after a 24" or 26" "Mens" sterling silver neck chain. I would like a weighty one that is pretty solid & 3mm or over. Have you got any ideas?

I have looked on Ebay & Amazon & they tend to be stuff that is as thin as a piece of A4. The same as HSamuels & Argos who charge an extra £20 for the priviledge of buying from them.

Help is welcome. Thanks
