I think this is the most affordable sample sequencer hardware you can buy right now, used or new (you might think that the pocket operator is less expensive, but since new units are not available right now, 2nd hand market went up and pass over the volcas). It had some missing features, like the possibility of record the actual samples (that's why is just a sample sequencer and not a sampler/sequencer), but is still a great option for those who want to try this kind of gear, even more this new version with the usb port.
Excellent value, intuitive, and very fun. The partner app to capture your own samples is equally straightforward. Add in the portability and it’s hard to beat. This is the all in one groovebox of the volca series
