Silicone Case for HP 50G

[zx_spectrum]

look, let's face it; the 50G is flimsy piece of chinese plastic that really feels like a cheap thing in hand specially when compared to 48G and other old hp's and yet there is not a lot of 50G out there and guess what!! they are freakishly crazy expensive so we better be very careful with the ones we have.
and once these are gone you can kiss RPL goodbye

I personally don't mind dropping over 50$ (heck maybe 100$) for something that gives 50G a real heft and makes it feel like a nice 48S/G in my hand
and of course I don't expect something disgusting like TI silicon case mentioned above, that is why I was talking about digital multi meter-like rubber maybe something permanent or screw-fixed at least.
it gotta be thick, heavy-duty and sturdy; something that would give some heft to the the rather cheap hollow original case
you know what would be even better; building whole new substitute swap case for the 50G but i know that would be difficult..
