Anyone here have any experience with CD Carousel's now or in the past? If yes, please tell me any pros or cons they may have. Any issues with mechanical failure? Most have 5-6 Slots, but I'm looking at the 50, 100, 400 and 500 just to get a taste of what's out there. The 500's are pricey as f*ck at $1k and will not be coming home with me any time soon. Most likely would shoot for 50-100 range.
