What's the most overrated or overpriced piece of equipment you own, have owned or come by?

I have been really fortunate in my audio purchases, not a single one I regret.

Having been in the retail end of the high-end audio business a long time ago, there were items that had high margins, like speakers (usually 50% profit margins for the dealer) and certain accessories, like cables, which had even greater margins.

Since I discovered Audiogon, I've purchased about half of my equipment from sellers on the site, finding good values on current models, great sellers who have accurately described the items they sell, so when I "flip" something, I don't take a bath on the ownership.
