I found a relatively new power cord recently, made from NOS Western Electric wire, that is a bargain in sonics. This cord has been favorably compared to cords costing many times its price. I bought this on Ebay and am including a link to that ad, but here is the web site for more info. I'm not affiliated with the company other than being a happy customer.
