This may sound a bit minimalist, but you can buy a 300Gb-512Gb firewire drive
for $300-$500 or so. Make it into NFS mounted volumes presented from a
laptop. Copy files to it, pack up the laptop and the drive(s) and then just
drive to the other facility, repeat process in reverse.
Sound far-fetched? I did exactly this with a 200Gb "secret" government
database last year, except I had to fly between data centers (won't explain
almost getting cavity-searched at the airport for booking a one-way ticket on
short notice!). Overall, this worked faster and better than all of the other
more elaborate plans involving temporary T1 lines, rented/loaner storage
arrays, etc...
Keep it simple.
