I haven't used the DJ, but I can tell you that the Zen Micro is, imho, great. I like mine very much, good sound quality, good looking, etc. But if your going to buy a Micro because you want an FM tuner on your MP3 player, don't. I can't receive about half of the stations here, and the other half only work on a good day and even then are full of static. Assuming that the sound quality on the DJ is as good as the Micro then if your looking at one of these 2, you can pick up a 20 or 30GB DJ for the same price as a Micro (depending on Dell's Deals) or save some money and pick up a Pocket DJ.
