I think there are many reasons you don't see tapers using any of these cheap mixer/recorders.
Now, I'm not very knowledgable about these types of things, but it looks like you can only record two mono tracks at a time since it only has two mono 1/4" jacks. This particular unit also doesn't have any preamps or phantom power and only records 16/44.1. Looks pretty terrible for what we do (and for what anyone does really).
