Cheap is subjective. You can get good and cheap at Radio Shack. What is your budget? There are alot of stores off-loading their old Audioquest (Topaz, Jade, etc) at about 40% off retail if you call around. There is also a DIY guy on Ebay who sells good cables anywhere from $30.00 for PBJ look/perform alikes to $80.00 for look/perform alikes Heros'. If you go to Ebay search on Cableplex. I have 4 of his PCs. At $50.00 per, you can't beat 'em.
Happy hunting!
