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

Back when had some vintage gear, I had Pioneer HPM100’s and JBL4312’s. I walked on my lips to get them and found I had a sensitivity to a resonance in their midrange area. Both found happy homes, but I wanted to like them!

I was also lucky enough to have owned (second hand) two Rotel disc players that quickly developed laser problems. When I called the Rotel distributor they basically said I asked for it by buying preowned. I took it like a man, but was somewhat surprised by the conversation. Overall my preowned purchases have been great, thankfully.

I told an untruth in this thread, my apologies.

I complained about the wrong manufacturer. Careless on my part. 

The brand I had reliability issues with was Arcam. (both lasers)  I was not the original owner of either. I called Arcam and a lady basically said I should not buy used gear. So I stopped buying used Arcam gear like the lady said.
