ripping vinyl using hercules deejay trim 4et6

hi all, has anyone hooked up a turntable to the inputs on the trim 4&6 to rip vinyl onyo their computer via usb? if so, how did it go, are there any gotchas to watch out for?

im currently trying to decide between buying a turntable with a edicated usb output, such as a pro-ject essential usb, or an ordinary turntable such as the pro-ject genie mark 3, and using my dj trim to do the analog to digital conversion.
