Hasko,
When it's available,go check out the Casio WK-3200
Word has it that this is the BEST sounding Casio to date and you will save a ton of money to boot-
When we get the 3200 into Sams sometime in the next few weeks,it shouldn't cost much more than $300 US.
Casios website(US) says $349...
Good Luck!
