I purchased the RCA Pearl MP3 player last year, mainly because the cost caught my eye - it was the cheapest MP3 player in the store. This little device is absolutely perfect for my music and work needs - I can store a few dozen songs on the device, as well as digital file for class that need to be edited or printed. More than 512 MB would be too much. I fully recommend this model for its cost-effectiveness, its utility, long-lasting power and convenience.
