I agree with @firstgrowth's suggestion about making your own, and it's satisfying to have done it.
I've made quite a few pair and found the Vampire Wire RCAs to be the easiest to work with and very good quality. Those, along with some shrink-wrap tubing and some Mogami microphone cable, available in bulk online, make a very nice pair of cables at a very low price.
If you don't want to do the work yourself, these look like a good alternative.
