Query: DO NOT BUY!

when it worked, it worked great, but after about 2 weeks, the screen went black and stayed that way. luckily, i bought it used for cheap. unluckily, that voided the warranty. last sanyo product i will ever buy...ever. cant even find a place in my town that sells or can fix them. not willing to pay 200 dollars to get it repaired by the company. big ripoff. really pissed. i guess ill just have to live with throwing 350 dollars out the window.
