I've been looking at these recently as I want to get one for a friend as a birthday present as he is always pissing around with floppy disks.

While the Sony and Iomega models are some of the nicest looking, Lexar and Plextor have recntly started doing USB2 drives. I've also seen drives with bult-in fingerprint readers (I think they were by Sony).

The cheapest drives I've seen in the UK are PQI 'Travelling Disk' models which ebuyer.com have listed at £25 for 128MB. Bargain.
