Need speaker cable recommendations ...

Anyone have experience with speaker cables for Lexicon MC-1, EAD Powermaster and Dunlavy Aletha speakers. The usage will be 50/50 HT/music. I am happy to buy used, and would prefer to limit the cost to no more than $500. I need 10 ft length. Some threads suggest simply going to Home Depot or Radio Shack. Kimber Kable 8-TC seems to pop up on many threads. I am bleary-eyed from reading the Dunlavy "Cable Nonsense" threads and see points on both sides regarding the Z-6. I understand the final decision is personal preference, I'd simply like to know if others have gone down a similar path and where they ended up. Thanks.
