Switching resolution on the PS3 isn't too complicated, but if you're trying to do it from memory on a TV that's blank because you've got the wrong settings it's nigh impossible. With the XCM E-SETER, you can quickly push one of the labeled buttons and switch quickly and instantly to the desired setting, bypassing all that Sony Cross Media Bar goodness their programmers worked so hard to port from the PSP. $29.99 [£14] is a bit too much if you rarely use this, but if you're taking your PS3 to your friends' houses to show off how great Heavenly Sword and Folklore are, you probably stopped reading and ordered this already.
