I have a 350E and also use the Customizer software. If I can help, I will, gladly. My machine isn't in that series, but the software is probably about the same.
I found embroidery on the 350E very, very easy. In fact, I couldn't imagine it being any easier. I bought the machine used and the lady spent about 20 min showing me the machine and how it works and left her email address and phone number if I have any more questions. But it is pretty self-explanatory. I think that your machine, however, is more complicated, and thus leaves a person with a lot more questions!
To answer your question...I'd attempt to learn how to use that machine, which is still selling for 2K than buy another one. Do you have the card you need?
