I have a Toshiba Protege R835. Though not super light, it's light enough for me to carry back and forth to my volunteer work and has enough connection ports so I can hook up to an overhead projector, which was vital for me.
Plus it has a DVD drive, which I know for some is not important but I find very handy to have.
It seems like my model is already outdated the but next generation has the same if not better features. Looks like a solid set of specs will still configure one for under $1000:
