Si I've been using a wireless microsoft mouse for over 6 years and the left clicker is starting to give me problems... it's the only mouse I have, so I can't currently play any games or do much on the computer. I won't have more than 30$ in several months and I need a mouse ASAP. I mainly play FPS and MOBAS.
So these are the options so far (If you know any mouse that's better in that price range please let me know)
Cobra E-3lue High Precision Gaming Mouse with Side Control 1600dpi
^Really like the design, has good reviews and it's dirt cheap.. which makes me have doubts on how good it will be.
for me, i'd choose between the perixx and the razer. the perixx is a good mouse because of the buttons (moreso than the others), but it you aren't going to use them, i'd buy the razer. razer are all about quality and i have never been let down by any of their kit (have around £300 worth of it attached to my PC at the moment). bear in mind that looks don't really matter, as your hand will be covering it.
on a side note, as long as the mice are all reviewed as being reliable, i would personally go with the one that fits your hand best. that's what makes a good mouse!
