I think you mean "20S", not "20C", and it was discontinued a few months ago.
As far as the closest upgrade/equivalent to the 11C, that's easy -- the 15C! (discontinued 1989, but available for < $200 on eBay and other resellers.)
They look virtually identical, but the 15C adds matrix functions, *good* complex number support, solve (real rootfinder), numerical integration, more RAM (448 bytes vs. 210), and more programming resources (flags, tests, labels). The 15C has *everything* the 11C and old 34C have, and then some.
Another reasonable alternative is the recently-discontinued 32Sii, which is faster and has alphanumerics and other features, but lacks matrix functions and has pidgin complex-number functions.
Take a look on the MoHPC site.
