I just finished buying this one:

It'll connect an HDTV, router, BD player, DVD recorder, 2x VCRs, 2x TBCs, capture system, IPS monitor. Never all powered at once. That's my personal setup, far closer to what most folks here would be using.
It should provide enough power to finish open tasks, end tasks without rushing at a power loss. I do stop captures within 10 minutes. I'll stop watching TV within 15.
Plenty of power to keep all items powered off, just battery. AG-1980 decks are touchy, so this is important. If power off for more than about 4 hours, then it'll fail, shut down, cut power to the vampires entirely.
