Philips DVP5990 is one option. They can be found either region locked or region free. The region locked ones go for about $55 and up at NCIX, Best Buy, etc and you should be able to hack it yourself to be region-free (I can't guarantee it though). The DVP5990 can also play DIVX avi's. It can also play videos from a USB stick/drive.
