You'll suffer from a lot of misclicks with red switches—specifically when you use a lot of keys, not just two, like z or x. I've been an mmo gamer and a writer for quite some time and I switched from red to blue switches after tons of pvp rage-losses from miscasting and tons of typos while drafting for my blog posts.
I'm just speaking from experience here, so take this with a grain of salt.
My first keyboard was a brown switch type and it was okay compared to reds, but are so different from blues. You probably won't notice the tactile bumps when you're clicking really fast, so it poses not much difference when it comes to gaming, but can be quite noticeable compared to reds for typing.
Razer Blackwidow Stealth (Tournament edition much cheaper) is probably the cheapest "brown" switch keyb you can find here, given that it's really accessible anywhere, mostly from SM Datablitz or PC retailer shops.
