I use a
Deathadder[The 4G one has a blue one I think, at least mine is]. Some mice depend on the style of grip you're using on your mouse, and sometimes the mice aren't accustomed to your type of grip etc. eg. My grip is a claw grip, but not exactly sure because I partly touch the mouse with my upper palm and I also use fingers.
If you are a
heavy mmo gamer, I recommend the
Razer Naga or a
R.A.T MMO 7, both have tons of macros, the R.A.T also allows you to customize alot of the parts, thats the beauty of Cyborg products, you can also check out their keyboards.
Keyboard,
if you want mechanical I strongly discourage a Blackwidow, don't listen to that 'RAZER IS DA BESTU!' BS. I have a
CM Storm Trigger[This is red, but has awesome lighting modes.] atm, like above, pricing at about 120. I enjoy it so far, but it really depends on what you like, took a while to get used to because the macros are on the left which didn't exist on my last keyboard.
The DAS Line are good keyboards which aren't flashy and are just simple mechanical keyboards that last long.
-NOTE- IF YOU'RE GOING TO GET MECHANICAL, RESEARCH THE TYPE OF CHERRY MX YOU WANT, I THINK FOR GAMERS THE SILENT REDS/BLACKS ARE GOOD. I USE BLUES WHICH ARE LOUD. BROWNS ARE IN THE MIDDLE.
Still, I think you should get mechanical if you have the budget, because once you go mechanical you can't go back, the feelings of the keys are somewhat different but unexplainable. If you are able to go to a nearby keyboard shop, try some of the ones that look appealing to you, if you can type perfectly on those you can decide to get it or not, you wouldn't really need macro's on a keyboard, you have function keys and numbers.
P.S.I'm sorry if I didn't read :P Was in a hurry and did some quick forum checking.
