I have the Tournament Edition Chroma and I've had it for about 3 months now, it's a great keyboard even with the Razer green switches. They really don't feel much different than Cherry MX Blues.
I've been using the Blackwidow/Blackwidow TE for months now, and I was a die-hard Cherry MX blue fan... the switches really aren't that much different. You'll like them man, any chance you can try out the blackwidow before you buy it?
Buy from the website itself, don't buy from third party sellers, even if they're from the same country/region as you. You're just asking for a headache.
