I have just purchased one myself. So far I love it. Between my job and my family, I have not been able to work with it as much as I want, but, what I have done has been fun. I am still trying to figure out all of the features and how (or if) I can utilize them. I have never recorded on any other multi-track unit before. I find that this unit is pretty easy to use and I haven't had any problems with it.
I have not seen a web site dedicated to users either. good luck.
