I was thinking of a Microsoft SideWinder X4 + Logitech MX620 this combo is around 120 NZD (87 USD)
or should i get the Logitech MX518 which is cheaper then a MX620(Not a gaming mouse)
I do some gaming maybe 65% of the time and the rest is browsing the web or doing some productivty stuff
If you have any other recommendations please inform me about it
An MX-518 is a no-brainer great mouse for gaming and anything else plus they're cheap now.
Look for a logitech G110 keyboard on sale.
Purchased mine for $65 Canadian taxes included.
I also own a Razer Deathadder which is also a great mouse.
