7100 or 7200

[mpyr]

Hi,
another dumb question from me. sorry :)

What is the difference between the 7100 and 7200 receivers? I have been told it is only hard drive size. Are they in fact identical except for that? What I mean is, the 7200 is referenced as being the receiver to buy but not the 7100. Does this mean that the 7100 is more susceptible to ecm and other factors that the 7200?

I apologize for the lameness of these questions but I have not found anyone who could answer that question and I have read a great deal on this board and the web itself.

Thanks in advance,
mpyr.

They are the same except for the hard drive size,,,Trust me,,,I own 3 of them. the 7100 has an 8 gig, and the 7200 has a 20 gig. Other than that, they are the same.
