I think that with blues, you need them on the right board, and yes, there is an adjustment period.
Until I got my Das with blues, I was sure I wouldn't like them. I didn't like how they felt when I tried them out on a BlackWidow in a store, I didn't like any clicky switch that I'd owned (of either ALPS or buckling spring type), I didn't like the sound of the blue switches in videos...if it weren't for coming across this keyboard for next to nothing in a thift store, I doubt I'd have ever given blues much of a chance. But now that I have it and am using it, I actually rather like them. I haven't had much gaming time so far since getting them, but so far, they don't seem half bad for the purpose-- and the click does make typing more satisfying, though I'm not sure yet if it's actually any faster or easier for me to be typing on the blues than on blacks.
So yeah, I would say that blues are certainly worth a try. Even if you're looking for something cheap with them, though, surely you can do better than a Razer...
