i really don't use either anymore after i started makin beats with software so im tryin to sell both if i get a good offer. The 404sx is in great condition, i only used it for about 2 or 3 months. I also put a 4gb sd card in it. The 303 is in good condition and comes with a cf card, ill have to check the memory. I can also post pictures by tomorrow.
I also may be willing to trade for other music production related gear
