Query: The Rio 800 really isn't worth the money

Why? Simply, I've had my unit replaced three times, I'm on first name terms with a sympathetic technical support (who, I'm afraid, are only available 8am till 5pm with no toll free number), I've spent hours on this, but I still haven't had a machine that works. So, is the Rio worth it? No, but my time is, so I'm going to get my money back and look elsewhere. I suggest you do the same.
