I'm looking to a add secondary 3.5" HDDs into a couple of Dell Precision workstations that I support.

The units have the facility to mount a second drive of this size, but the plastic caddy is only provided for the (factory-fitted) primary HDD.

I initially thought that these would have been fairly common but I can't see them as spares on the Dell website and although I have come across a couple on eBay, the shipping costs make the proposition somewhat ludicrous.

Does anyone know of somewhere that these could be obtained locally?

A link to the type of unit I'm after is http://www.ebay.co.uk/itm/Dell-U6436-H7283-G8354-YJ221-N218K-Hard-Drive-HDD-Caddy-/260755929353

Many thanks
