Forgot to mention. I was thinking about what to do with the 3x these last few days. This morning I got a private email from a friend here in the Zone advising me the OS is pretty similar on the 3x and 4x. So I made the decision to start learning the 3x (before it decomposes) and if I like what I'm hearing, I'll purchase the 4x but this time a 61 key.
