Most of these cables may be priced above your budget, but perhaps used or stretch your budget may be an option.  I picked up a few Kimber Palladian PC used because of their price/performance seemed ideal for my budget.

I must agree with many of the previous posters, Signal Cable, Cullen Cable,and Cerious Tech. are all excellent choices. If I was not flush with PCs l would be taking a hard look at Take Five Audio also.
