So I'm at the point where I have no choice but to buy a pc. Now the question is: Which one? I've found a solid steal on a pc3 EX, the pc3r is by far the most affordable, but everyone seems to be using the pc3 usb. I know the EX won't allow you to make changes in the low range but is that part necessary? Also, from what I can gather from other posts, all that's needed for the pc3r is a conversion cable that'll connect to a usb port to change the settings. So should I save the money and go cheaper or is it not worth it? GPW, I would REALLY appreciate some input from you as well as anyone else with solid info.
