I'm looking for a laptop and presentation projector to do some outside presentations to people in my community, as local groups are requesting these talks. I do these presentations on powerpoint. I'm looking for a combo that gives a nice clear output without going nuts on price, since this is all I use it for.

Can anyone recommend a good projector at a good price? As I said, I don't want to pay top $$$, but I don't want a crappy output. Also, is the video card going to make a difference in this case (integrated GMA950 vs. 128mb dedicated vs. 256mb dedicated)?

Thanks in advance.
