"Dear Friends, I couldn't play my favorite record since I no longer had a turntable. I was so happy to find out about you. I was delighted with the speed and quality of your service ...I hadn't expected that the CD would be of such high clarity. It's a bit pricey but oh well, it's worth it. I would recommend you without reservation to anyone."
