Compare those two brands to Alienware and you'll see a lot of similararities. I've used Pro-star notebooks with no problems.
Also, don't look at only "gaming" laptops. Hell, about 2 years ago emachines had the best bang for the buck gaming laptop out there. Nice vid card, nice proc...nice display...etc for like 1200.
If I had to buy another "gaming" laptop I'd start with pro-star or sager...then dell, then gateway.
