Indeed, it's the most you can get for the money if looking for some standalone product, but still very limited. Of course, for TE-PO users, it's gonna be a giant leap, but it's not a serious production instrument. Construction is plasticky, keyboard "keys" are wobbly and sort of rattly. Battery life is around 6 hours using lithium batteries. Overall production workflow is incovenient, very far from some other workflows I've been used to. Using parameter locking function does the job, but makes the workflow crazy annoying. If someone asks me, whether he shoud buy this, I say NO. It's better to wait and gain some more money and get SP404 MKII.
