I love this thing. Was able to get back to my records. Picked it up for about 110 a year ago on ebay. I use it to listen, and sample. I record it into my computer via usb + audacity. I also record straight into Maschine or Fl studio sometimes. Works great. I wouldn't recommend starting your DJ career with them though. At least get the 120s.
I've had mine for a few years, not a single issue. The USB connection is nice if you need to transfer your vinyl collection to digital (if you are like me, and only DJ with a digital setup). At the office, it functions as a simple player. I have a really nice amp and 5.1 speaker system, so maybe it's hard for me to judge, but the audio quality sounds great - and I'm using the needle from the factory right out of the box.
