Just bought the
Ion iTTUSB. It's also available under the Numark name (the Numark version adds a pitch control). Cost me $130 at Best Buy. I got it for sampling purposes. Amazingly although it looks like a pro table in pictures when I was face to face with the display model it was 100% plastic and weighed almost nothing. I think the counterweight is the only piece of metal other than the screws
It does what it is supposed to do, it even has an 1/8" line input so you can digitize from other audio sources

It has both phono and line level output as well as the USB so you can interface to analog gear as well. The cartridge supplied was different than the one shown in the manual and on the demo unit, I think it might be an Audio Technica, in any event it's very low end. Sound is OK but a better cartridge would be an improvement. It also has no cue lever, you have to cue by hand
OK for the dough but it's no Technics or Thorens table.
As far as playing through your computer, after only one day with the table I have been unable to get it to play through the computer. I can record into audio apps fine and play those apps back but Windows XP so far refuses to let me monitor the audio in real time while the apps are recording it. As a mostly Mac person I find this par for the course

The XP audio control panel will not allow me to select one audio driver for input and another for output. This is not the fault of the turntable of course, just another reason why I feel computers still have a way to go before you can
really use them to replace your stereo system
