I bought one of the Mix Sticks last year on sale for about $20, then later Sears Online had the Mix Max on sale for $25 and I bought 2 of them. The mix stick is definitely not worth $40 to me. It has minimal room for songs, you can expand it with an SD card, but you can't choose what song you want, you can't see what's on it. Hold out for a sale on the Mix Max, you can put pictures and video on it, and you can scan your playlist and see what you want. Like PP mentioned, you can rip any CD's through Windows media player and drag the songs to the Mix Stick or MixMax, or if you don't already have the music, you can buy it online yourself, but mainly we rip existing CD's and put on the MixMax. The Mix Stick we currently just use on the treadmill for listening to music while walking.
