I'm very happy with my Sager. Not well known, but pleased with their support, top notch components, value pricing. The one I'm typing on now I bought 5+ years ago, has a 15" screen, numerical keypad built on the right side of the alphabetic keypad, and is built commercial tough. It cost more than you're looking for, but they may have some that don't.

Reality is, you may need to consider pre-owned laptops to get your features and your price.
