I purchased mine for 40 bucks last Black Friday online including shipping. Your present setup consists of Mouse and Keyboard, right? Assuming you a right handed Mouse user, what does your left hand Thumb do, anything? With this little gadget you can create up to 10 hotkeys programmed to any key you want just for that one single thumb! You can also macro multiple keystrokes with one button!
If you are the type to invest big bucks for a video card to get the pretty graphics but don't invest in awesome user input devices like this, you are selling yourself short!
