MFB-522 vs TR-808

More and more realizing I need a proper analogue drum machine (since the Monotribe does have it's limitations) I have been sizing up the competition. Leaning heavily towards an MFB-522, since it's basically the only decent thing I can afford (and it's small and portable). This shoot out between the 522 and it's more famous role model hasn't turned me off the prospect of getting one of these.
