Zu Cable regularly auctions their Xaus tonearm cable on eBay starting at $150. If you catch the auction right, you can buy one pretty cheap - I got mine at $150 as the only bidder. They'll terminate it any way you want; mine is RCA-RCA and sounds great on my Well Tempered Record Player with my Denon 103R. A huge improvement over the standard interconnect I was using.
Here's another option that was going to be my second choice if I didn't get the Zu:
