Okay, so I've been looking around for a good, relatively inexpensive HU for my 72 Stingray. The Kenwood EZ-500 is very appealing to me, since it has the aux input I need, has gotten good reviews, and has the retro two-knob design that won't look too out of place in my car. I was just wondering if anyone has any experience with this HU - good points, bad points? Possible (better) alternatives?
