Keys action on EXR, EXR-s, and GW-7 ?

Dear my fellow friends,

Does somebody know how's the comparison of the keyboard (keys) action between EXR series, EXR-s series, and GW-7 ?

Which one has the best keys (solid, straight, doesn't feel like a cheap plastic) ?

Thanks a lot

Rolandlover,
The EXR7s is the best key feel by far. The GW-7 has very tiny keys, like an accordian. Also, the EXR3s and 5s don't have the goodies that the 7s does, so for the extra money, I'd go with the 7s.
