Is purchasing a steelseries xai a good idea? It's specifications make it both useful for an fps gamer as well as an MMO gamer. It doesn't look amazing but it doesn't look ugly either. My other options are a R.A.T 7, A Razer Deathadder or a Logitech G700. I'm not so sure about the R.A.T as the more I look at it the more I think it's a overpriced gimmicky mouse. I'm sort of put off by the deathadder as I have a razer mouse already and it's matte covering is already coming off after a year which puts me off razer and the deathadder only has 2 bonus buttons which isn't optimal for an MMO. Finally the G700 I looked at recently looks like a solid contender but it also looks like it wouldn't be as optimal for an FPS as the Xai would.

Does anyone own a Xai and can vouch for it or dissuade me? Or perhaps offer advice on the other mice? My thanks if anyone can help.
