Optimus MD-1200 - A nice mid-range keyboard from Radioshack. No longer in use, but I used it almost exclusively on the Dark River album. Since then I've only used it for the odd bit of piano or strings (which are its strong points). Most of the sounds are fairly cheesy, but they do have some editability which provided some of the more interesting pads on that album. I also used it as a controller keyboard for my VSTs and Fruityloops until I picked up the Casio CZ-1000.
