Wanted to add that a G4 iBook (12" preferably, 14" would be considered) would also be something I would look at. I also MIGHT be interested in a 12" G3 iBook if the offer was right.
Lastly, a combo including a midspec gaming PC could be possible, as long as it included at least $500 in cash and a display. Or at least $800. and no display.
Combonations of all these (iBook ow Powerbook, mini, LCD, gaming PC, cash) is good too.
Thanks to all the people have responded so far.
