Can you ever own too many instruments?  

Yesterday a friend stopped by to tell me he had found an add on Craig's list offering an accordion for sale. The person said it was hand made in East Germany and he didn't know the value of it but wanted to sell it. I went to take a look at the instrument and am now the proud owner of a Max Grimm Piano Accordion. My wife wasn't too happy as I already own Three Milton Mann DaVinci Accordins, Four Horner Accordions, A Universal Accordion, A couple of Guitars, A Trumpet, and a Grand Piano. I told here that unlike cars and other items Musical Instruments do not really lose value but become more valuable over time. Besides, I play all of my instruments on a regular basis. She said that I own too many instruments. I don't think you can ever own to many instruments! What do you think?
