Casio MT-45
The pretty and substantial Casio MT-45 looks similar to the Casio MT-60, but its hardware is completely different. The accompaniment section is basically a pared-down Casio MT-68/100/400V, although the analog drum circuits do sound a bit different. The chord and arpeggio sounds cannot be altered and only two variations are available for the bass.
As I already own similar keyboards, I haven't tried any bending, but due to the hardware, a whole load of modifications should be possible.
