I've been torn between getting something high end and a cheapo line out adapter. I have a middle of the road setup, and want something in that range for hooking up my iPod. Found the CableJive +USB Line Out Cable, and it arrived last week. By no stretch a hi-fi solution, but does the trick for me. I generally don't use the USB part with my home stereo, but is nice to have if I want to charge at the same time I'm listening.
