Hey;
a few things, in order.
1) i have bought 4 razer mice from eBay - none were fakes. some were cheap, yet they worked perfectly, took razer drivers and are worth the money, yes.
2) the deathadder has been, for a few years now, the n1 mouse for mousesports. weird shape, heavy, but great sensor.
3) razer quality used to be worse, now is on par with pretty much every manufacturer out there.
4) mousemats tend to offer as much, if not more, advantage over casual users, as gaming mice do.
i recommend the goliathus CONTROL edition, get the Large one. from ebay or amazon.
5) if you can spend just a bit more, grab a Zowie FK1; i just got mine and it's gotta be the best mouse i have ever laid hands on. better than the DA, Abyssus, and G400s. even better than the WMO 1.1a with overclocked ports.
