I have the opposite problem with many of my cameras, my wife wants some left on display when not in use - in Turkey and each tome we travle back from the UK wants me to take others !!!!! some have just been restored and are still untried so that's not on. I recently managed to overcome this when I found a bargain box of cameras at a camera fair and bought duplicates at £1-£3 each, but that also threw up jewels like a mint Zorki C and a very nice post WWII Ikonta, so ironically that makes it worse.
My biggest problem is going to be explain the whole plate camera I have sat waithing for me to collect in 2 weeks when she knows I've two others bought as parts plus another early half plate camera that just needs new bellows. I guess the upside is they are worth mor5e than I paid for them, an identiacl half plate camera again missing its bellows sold for more than 3x what I paid, and its the same for the whole plate camert.
Luckily I am picking up cameras at camera fairs and flea markets very cheaply and usually restoring them so they are worth significantly more than I paid, even more if I sold them in the right places in Turkey wher old cameras are real collectors items.
