My LCD has never let me down, it's been a great marker, and the IR3 really doesn't have THAT many new featuers over the LCD. For the price difference, the LCD is cheaper and just about the same. I would recommend the Speed over the LCD if you can afford it though, the Speed is a little lighter, a little shorter (same size as the IR3), lower pressure and much faster, and they're only $800 from just about any retailer now.
