So I ordered one of these things off ebay and just got it today. I plugged it in and right away I knew it was going to be a good piece of equipment. I love the sound of the preset patches. And its so easy to make your own! The sound quality is very good. Its quite easy to navigate and the drum machine is decent. The display could be better, but it gets the job done. I think this is a very solid piece of equipment for the small price of $100.
