Magicforce (also sold under the Qisan name) has an aluminum (exposed) plate.
Just so the OP knows,
An aluminum plate in an plastic case is NOT the same as an full aluminum case.
It may look nice, and it can even work/feel nice (due to metallurgical properties), but it is nowhere nowhere near what a full aluminum case with a solid mounted plate (like the Filco/Vortex) feels like.
Don't get me wrong, I love the Magicforce, in some ways more than the Filco/Vortex (and that is ignoring the price), but if I were to accidentally step on both, the Magicforce would probably be ruined, while the Filco would ignore it as if nothing had happened. Drop them on a desk, the Magicforce would bounce and fall off, the Filco would break the desk (mine is glass). And as for typing, again, I like the Magicforce, it's sporty and light, like a Mini or Miata. The Filco on the other hand is a Bentley, big, fast, heavy, and oh so luxurious, but with a price tag to match.
