Constant Popping Sound

I've run JVC HUs exclusively before this Eclipse that I bought and the only problem I seemed to have was with the mechanical face in the cold and an odd intermittent problem with the buttons after about 2 years of hard use.
So I'd vouch for either company.
And like the other guys said, you're going to get a longer use out of a higher quality HU. When we talk about quality of a product, we're generally referring to failure rates and longevity.
