I don't have one but I'd definitely take a tape changer if it weren't too expensive. It would be amazing to have 72TB of storage just waiting to be filled, without needing to go out into my garage to load a tape up.

LTO tapes have really changed my life, or at least my mental health. Easy and robust backup has been elusive. DVD-R was just not doing it for me. Hard drives are too expensive and lacked robustness. My wife is a pro photographer so the never-ending data dumps had filled up all our hard drives, and spending hundreds of dollars more on another 2-disk mirror RAID, and then another, and another was just stupid. Most of the data will only need to be accessed rarely, but we still want to keep it. I lost sleep over the mountains of data we were hoarding on hard drives. I've had too many hard drives just die, including RAIDs being corrupted. LTO tape changed all of that. It's relatively cheap, and pretty easy and fast compared to all the other solutions. It's no wonder it's still being used in data centers. I love all the data center hand-me-downs that flood eBay.

And I do love hearing the tapes whir, it makes me smile.
