Well, SPDIF stands for Sony/Phillips Digital Interface and there are actually three common types of connectors for them. BNC, Toslink (optical), and RCA.
And what's wrong with Radioshack for something like this? For cables that transmit analog signals, you want something that keeps the noise and interference down. For SPDIF, however, it's a digital signal, so as long as it transmits the 1's and 0's properly, the sound will be the exact same. Just make sure the impedance is 75 Ohms and the connectors are RCA, and I can't think of any reason why you'd have a problem.
