Are we paying too much for 10-gigabit ethernet buildout for a cluster?

We are working to reduce io bottlenecks on a 30-node LSF based cluster talking to netapp nas. the clients are all on gig-e, and with 8 cores each are capable of handling much more than the ~70MB/sec of throughput they get now. We are looking to simply switching up to 10GB ethernet and a roughly 8x amount of increased io, but the costs seem outrageous. Our sysadmins are saying it will cost around 4K/port end-to-end (including switch, nics, fiber adapter). I'm not a network guru but this seems high based on parts I see on other corporate websites for equipment. One area of contention is wether we need fiber or copper. My understanding is CX4 is fine and has all the performance of fiber as long as you are under the 45-foot limit.
So... 1) is that pricing nuts and 2) is copper okay for lower distances?
