Yours probably still use Cherry MX switches then. Fairly sure that Razer only started using their own this year, older ones use Cherry's.
Ok so you have 4 popular switches, Blue, Brown, Black and Red.
Blue are best for typing and games with clear key presses, for example Strategy, MOBA's etc. Blue's are extremely loud but you will always know for sure you pressed your key, because of that it gives you security of pressing the key that black and red don't give. They however are bad for games where you move around a lot, so shooters, MMO's etc, because you need to let go and press down again fully.
Red are best for shooters, MMO's etc, they are however bad for typing, strategy and MOBA's, they are also pretty quiet and don't give you that 'satisfying' clicking sound. They are basically the opposite of Blue.
Black is red, only require you to press down harder.
Brown is in between blue and red and is seen as the best overall keyboard.
And because of that, I would definitely recommend brown, I personally use brown myself and play MMO's, shooters and League of Legends, plus I type quite a bit. I personally use the Roccat Ryos MK Pro, which is a little above your budget, but there are 2 cheaper versions, the MK and the MK Glow. Other options are the various Cooler Master keyboards, although these are not gamer keyboards. There is also the Logitech G710, which only comes with Cherry MX Brown. Razer obviously has 2 mechanical boards, green is similar to blue, and orange to brown, they should be fine as well, so if Razer is the thing, go for it, in the end the quality is pretty much the same, at least I assume so, like I said, Razer switches are quite new, whereas Cherry been doing this since the 80's, so they have proven to be excellent.
Whatever you do, before you order, make sure you got the right switch. I had price comparison sites that would send me to the wrong keyboard, because the site in question had the wrong SKU (product number) filled in, and I would highly recommend the Brown/Razer Orange switches for overall gaming and typing. The rest of the keyboard is really down to preference. What style do you like, what buttons etc. The reason why I went for Roccat Ryos was because of the thumb buttons below the spacebar, getting those extra easy access buttons in a MMO is a real advantage imo.
