If you're looking to buy a genuine set, I'd get the IE80s from amazon.de for 215 Euros, or about $280.
I bought mine from there, genuine, for 209 Euros, and then shipped them over to Australia. Here:
Alternatively, you could negotiate with Razordog Deals and say you're a head-fi member, and try to get a discount. There's a $100 off coupon for buying a product over $399, but I'm not sure it applies to Senn products.
I like my IE80s a lot, so I hope they'll serve you well. Good luck!
