Just to mention in latin america the GW-8 has become a great success, it's actually consider the holy grail for arrangers over there, mainly because includes the best latin voices/styles ever release on a keyboard since GEM released their WK6 latino edition. Piano patches comes from fantom G series, and you have to listen that to be amazed, it comes short in some areas, but for the price who cares, there is no style editor built in, we use sonar for it, we use Style Factory Roland from SMC musicsoftware (99 euros AUCH) to convert all mayor styles easily to GW-8. that's a perfect complement for my PSR-S900 when I go live.
