Hi Yogurt,
Using just an S900 and a laptop(or a PC), you can make very nice CDs.
The S900's Audio to USB is a doddle to use, and the resulting recording is in WAV format.
The vocal mixes very well with the rest.
I make my own CDs using an S900 and I'm more than pleased with the results.
The S900 also has the benefits of awesome third party support, so there are plenty of styles available.
If you like "natural" sounds, the S900 serves up a nice helping of SA, Mega, "Live" and "Cool" voices...nothing in it's price range can touch it for sheer sound quality.
I'm a Yamaha aficionado, and my view is a tad skewed...but my information is accurate...and it is the "best bang for the buck" available.
Ian
