Bit-z is my favorite exchange.  Easy to use, and shows cash value as you make bids.

And DAMN that Bitcore network is fast.  Just grabbed a few more and sent to my wallet - went pending in about 10 seconds - was there in less than a minute. 

WHOOOOOOOOOOOOOOOOOSH - Nothing else I've used is even close to as fast.

Gonna pay my house off with this coin!!!
