Trusty 32SII dying - should I get the 35S or 50g?

[Logan]

I used the 35s exclusively for months leading up to the PE exam, and ditched it as soon as it was over (for a 42s). Random bugs, intermittent key presses, couldn't keep up with fast entry. I lost faith in it after a while and would have to constantly slow down to check my input.

Had some nice features (equation solver, algebraic entry for equations, quick access to variables) but I'd much prefer a 32SII or a 42s over it.
