That's like the ones I've found on ebay. I've now also found one that also has a SATA port on the top, so you can connect both 2.5 and 3.5 IDE, as well as SATA drives via USB which could be very useful. Plus it comes with an external PSU too so you can connect up 3.5" HD's and supply them with power. That one is £2.99 + £4.95 postage (£6.98 total) and the seller is in the UK, so I might get that one.
