@PigBoss well, Razer products are generally sturdy and bulky, but expensive. It is worth investing if you are a "gamer". I think Razer Deathadder has a proper hype. It is a bit overpriced, but it is pretty solid.
I tried Razer Taipan, because my brother has one. It feels like Roccat Lua but bigger. I don't find it that comfortable.
Now, Razer Naga 2012 had some really nice curve to it and it reminded me of older Razer models. It was very comfortable to use, but I couldn't afford one at the time, so sucks to be me.
The new Razer Naga is less curvy and more bulky, which sucks. Now when a fan of razer naga wants to get a replacement one, they can't.(fuck you razer, stop coming up with bulky designs)
Conclusion is, if you are into big bulky mouse, Razer Deathadder is a safe bet.
I heard corsair mice are pretty nice too, but I didn't try any at the moment.
