WD (Western Digital) Passport portable external is highly spoken of here. If Art's files are of the size they might be, a 2TB might be well worth consideration. Here, WAY OUT in the boonies of the Frozen White North Woods, 1TB $90, 2TB $150.

Dunno what I am talking about so those who do should speak to this... I had a thread on portables a short time ago and much help was offered.
