Keycool make some nice OEM profile medium thickness POM and PBT keycaps. They're quite cheap, too, but fortunately still good quality.
Also, I'm not sure if the bi-color Vortex thick PBT doubleshots are Cherry-like or OEM profile. I think their new PBT/POM backlit doubleshots are the same. Their older ones (with the italic legends) are OEM.
<Edit - discovered the Vortex sets are all OEM. The bi-color sets have a very tall F-key row />
