ESQ-1 keyboard and an E-mu
ESI-32 rack sampler. The sequencer in the ESQ-1 rocks and the ESI-32 is basically an EMAX III. Total would be less than $250(100-150 for esq and 75-100 for the esi). The sequencer on the esq is maybe the easiest and most intuitive ever made. No menus, everything has a dedicated button, everything logically laid out and it has a huge screen that you can read from a mile away. This is my second ESQ recommendation today btw.
The screen is LED, forgot to mention.
