For laptops, Toshiba. The Satellite L-series is a nice medium between "hair-on-fire sticker shock" and "meh, let the five-year-old play with it."
For desktops, HP Pavilions.
For retailer, Office Depot. For an extra charge they'll strip that excess software out of there, burn you some recovery discs, and make sure laptop batteries are correctly charged the first time.
