Back in the late 80s, I saw an ad in the Recycler for a garage sale. I was looking for some mic stands, and they were in the ad.
My drummer friend and I drove over, and an older lady showed us into her garage. It seems that her late husband was a TV/film sound man, and had some gear left behind in the garage.
As we were rummaging around, I came upon a box with a bunch of microphones in it. There were two Sennheiser boxes in there, and when I opened them up, I about had a heart attack! They were a matched pair of Sennheiser K2-U shotgun condenser microphones.
I looked at my friend with wide eyes, and asked the lady how much she wanted for them. She said "$5 each."

Of course, we bought them as well as some other mics and a ton of adapters, plus a bunch of mic stands.
My Sennheiser K2-U is still my "go to" mic for vocals, acoustic guitar etc. A fantastic mic! Other than a Neumann U-87, it's the best mic I've ever heard.
