Yep, wrong forum, and I doubt you'll get a P4 for $99 a month or under without a hefty setup fee. P4's aren't cheap. If you're lucky you'll get a P3 800 at that pricing without a setup fee, or a celeron, but I think you're more likely to get a Duron for that.
One of the better P4 offers around at the moment would be webreseller.net @ $170 a month with $25 setup. That would come with 400 GIGS of Yipes! transer, which is good quality stuff.
