What size screen for front projector?

Thanks for the suggestions. Stewart is the brand that he was thinking about. He won't be able to demo as we live 250+ miles from anything you'd consider to be a good a/v or HT shop. In fact he's buying the Sony sight unseen based on all the extremely positive reviews. He has $10k budgeted and the PJ is about $8k with tax, so he has up to $2K for a screen. Is there a visible difference between models? Is the Studiotek 130 noticeably better that one of their other models? I'll also have him check out avs.forumcom. Guess we know where the neighborhood Superbowl party will be this year!

Tireguy - thanks for the input. Yes, it's the VPL (Ruby) that my neighbor is buying. Now that you mention the fact that the PJ is not bright enough to do more than 100" at that distance, I think I remember reading a review that basically said that same thing. I'll have to look it up and give to my neighbor. I think I also read that replacement bulbs are $1,000!!!

Looks like the concensus is that he needs a screen around 100"D. and then should adjust his seating accordingly. Thanks for everyone's input.
