Tried searching for the manuals. Found the 50F Plus manual.
Is there a link for the manual to the 50FH II?

I have only the fx-50FH, I don't know the 50FHII. The keys are hard plastic, not rubber (on 50FH). I never saw CASIO without keycaps, I can't imagine who can remove keycap during normal usage of a calculator... The keys are moves (wobbles as you wrote) but they are fixed. I use them years without any problem. The keyboard contrast very well, just check the picture below. The shape of keys also well designed, totally same as 570ES (or 115ES) the 1st edition (not PLUS).

The 50FH looks better, IMHO (and better than the other programmable model of CASIO, the 3650P). In 50FH most of 3650P's bugs fixed and programming model upgraded (see the Comparison link below), eg. added structures like

If ~Then {~Else} ~IfEnd
For ~To {~Step} ~Next
While ~WhileEnd
Break


Some great commands are programmable, eg.:
DT (statistical data input supported, unfortunately data delete NOT!)
Access to Stat registers from program available! (means you can use more storage registers AND with n as a counter and DT you can make loops without other register usage)
