That's always the question, isn't it? I've got a nice little 7u and a M32 and it's a ton of fun with a myriad of possibilities. So much so that it's almost a hindrance. I find myself noodling endlessly, diving down into patches for hours only to arrive at the point of exhaustion when I just shut it down and go right to sleep. No recording, no song, just the moment I've enjoyed on my own with some headphones on so as not to keep my wife and kids up all night. I often wonder if would I be working more effectively on the backlog of songs in various states of completion with something less open ended like a Sub 37, or an 0-coast even.

Yes, you are on your way to building something more expensive and clunkier than a Sub 37. Is it worth it? I really can't say. I'm still trying to figure that one out myself.
