Travel to your friends house to play Guitar Hero or Rock Band? Don't like their worn out crappy guitar? Bring your own portable NEXiLUX guitar which collapses for backpack style portability. The NEXiLUX guitar even has the touch sensitive strip on the neck that Guitar Hero World Tour uses. Works with the Wii and PS3/PS2 and is wireless. Yours for around $50 if it is ever back in stock.
