Thanks Satsuki - Great advice. I have a 20TB lightning RAID5 setup I may use as a primary download device. It's heavy, big, but pretty reliable. Going to stock up on a bunch of 2GB drives as well for secondary backups per your advice.
I'm also planning on setting up a DIT cart with UPS for the RAID and for viewing footage on our HD monitor. Luckily our locations all have decent power, so no Gennies needed (we hope).
Mac Mini may come in handy as well possibly.
Cheers.
