Definitely get the impression a lower wattage inverter will work just fine for my needs. I do have one 280 watt, black-box device that I may have to use occasionally. So, I've decided to purchase the 600 watt Power Bright PSW inverter just in case I use it, my TV, and laptop at the same time...
...and even if you have to use bedroom-size LCD TV and laptop at the same time - don't know why would I :) - it is still less than 200W. As long as inverter can handle 250W continuous output - not peak output - 250W is all you need. But it should be
able to handle 250. Inverter ratings are not to be trusted, I've seen 170W rated going up in smoke when charging a working laptop.
Roy makes a good point though - people often can't control themselves. The recipe to avoid running "one more 120V item" (the proverbial last straw) is not to carry one. You are only there "few days at a time" as you said.
