Hola Agustin,
There's one that I do not know wether someone mentioned it or not: Toshiba Satellite 5000-S504,PIII 1.1GHz, 512MB RAM, 30GB Hard Drive, 15.0-inch TFT Display, 8X DVD / 8X4X24 CD-RW Drive, XP Home Edition for $2000, Powerful huh? Since I like Toshibas this would be my suggestion. Regards.
