Ok, last post of the night, I promise.

The iGo Juice 70 fits into category 3 above (the $120 category). See http://www.igo.com/Product_Detail.as...play=Technical

It's on eBay for $43 buy-it-now + shipping ($10 in US, and it says they'll ship worldwide):

I have no affiliation with them, but am going to pick one of these up for my iBook, since at $53 it seems like a great deal, and the iGo brand seems to have a good buzz around FT. I guess I'll report back in a few weeks after I get it and try it out on my next long-haul.
