Between Bachus and Dan, the Yamaha MODX88 sounds very appealing to me. It looks huge, but only 30 LBS. I can live with that. The MODX combined with vArranger... as Dan mentioned sounds good to me though I thought I would never buy another big workstation type of a keyboard. I am waiting for a new model that will replace Casio's PX5s or the PX560 but now I am considering the MODX88 also.
