MCXNow is pretty great, I recommend it even though they don't have a lot of currencies. They will add more in the future and in the meanwhile it is by far the fastest system out there, they pay interest, and you can switch into USD whenever you want.
I have no idea why people still use cryptsy.
MCXnow pump threads lately? I thought about them, but interest rates close to 10% when they're starting? Good luck getting a withdrawal, that's what that says to me.
