I quote from sonic state´s review:
"Eftychis Sifakis (sifakis@csd.uch.gr) writes:
This workstation´s main drawback is the rather old sound source it carries (SC-55). *The sounds are of rather poor quality*, with only a few exceptions. Nevertheless, although not being a unit of professional calibre, it is *equipped with a quite comprehensive sequencer*, with an ease of use that often makes me to leave aside my computer for most editing purposes. It could be considered a unit well-suited for beginners"
* * added by me
Based a search in prepal.com, the price of the JW-50 should be about Sin$530 to $550 based on condition.
If you are on a tight budget, go for it. If your budget is more flexible, hunt for something better.
