Non-graphing calculator supporting complex matrices?

Okay, I concede that memory may be a limitation (what the 34S couldn't do with just a little extra memory!!!). Still, there are sub-$20 calculators that can handle 4x4 real matrices (Canon f-789sga comes to mind---in fact this one's price dropped to sub-$10 at some point), so they have at least as much memory as needed to handle 4x2, and probably 3x3 complex matrices, which would be quite useful---and has nothing to do with asking for the ability to *graph*.

Then again, if students didn't use calculators to cheat I'd have no problem letting them use a 50g, which would be the best sub-$90 purchase of their life.
