If your budget is limited to under $200 for a bi-wire pair of cables (presumably 8-10 feet long), then you should audition the Kimber 4VS or 8VS. If you can find a set of used Kimber 4TC, then they should also be within your budget and will offer slightly better sound. (The only difference between the "TC" and "VS" lines is the type of dielectric/insulation used to coat the wires.)
If, however, your budget will stretch to accommodate a set of used Alpha-Core Goertz MI2, they are my first recommendation. Great cables for a very modest cost (by high-end standards).
