Tex, I'm in agreement with Sam. If you decide that the upgrade is for you, then what I can tell you is that going from a I to a III will be a BIG improvement. Sam is also right about the glass input - mine does have that (I use it with my Proceed PDT-3 transport which has AT&T out). But there are so few sources with glass out anymore that it shouldn't be a huge issue for you. The Toslink input is quite good, as Sam indicated.
BTW, that upgrade price is great.
