Looks like you have taken the advice from some of us here. Really, your best bet for a hot seller is a machine with 808/909 that actually nails those sounds. People want those sounds in an analog drum machine. Anything else is just less. There is a reason why the 808/909 have been the most sought after drum machines for the past 20 years. If you put both genuine 808/909 analog sounds into a single machine with a nice interface, sequencer and some extra bells and whistles like FX, at a great price, you will have a winner.
