A question about the blackwidow keyboards...

Hello everyone! I've been thinking about getting a mechanical keyboard for a while and, since I already have a Deathadder and a pair of Kraken Pros, I've been thinking about getting a Blackwidow! Now, I still haven't decided between the ultimate 2014 and the tournament but 10.0.0.0.1... I heard really mixed opinions about them and their "Razer switches"... So, what do you say Razer? Are them good keyboards or overpriced plastic? I don't really wanna spend 100€ euros or more on something that doesn't work the way it's supposed to...
