I would recomend this as very economical option.
The sounds available are awesome and the backing tracks and styles are fun to play around with. I like the ability to play along with my own song set from the USB Stick and have all performance parts output to the stage speakers. With this setup I can play like a full band or strip down the parts in the accompaniment and play along with other musicians. This is great for MIDI recording to my computer or recording to an external device or even in the i3 itself.
