hey everyone..im having alot of trouble figuring out which to get..i only want to spend in the $1000 range and im specifically looking for an 88 key, fully weighted keyboard and ive brought the choices down to these 2; yamaha s80 and the alesis qs8.1. im going to be using these to sample from onto my computer to produce hiphop tracks. can someone help me out with a comparison on these 2, focusing mainly on the different sounds that these 2 both have? including sounds/voices/instruments/bass/drumkits, etc...that would be most helpful! thanks alot,
