i use the g11 keyboard and the g9 mouse, both near top of the line and both work great. it really depends on how much and what kind of games you are intending to play on your pc. if you arent playing games that use alot of twich reactions its not really worth it, but in fps and other actiony games like that they give a definite advantage. one problem i had alot on fps is i would hit too many keys at once and the g11 fixed that, lit keys are also nice and macros are useful for common commands. you get what you pay for basically.
