USB Interfaces

Hi All,

 What is everybody running for USB interfaces ? I have a Roland UA-700 and a Line 6 Tone Port ( the single input version). I'm kicking around the idea of may be selling one or both and getting an interface that will let me record more than one track at a time. Is anybody just using a USB mixer instead ?

Is that a rack unit ?

Halfstack, I just bought something today that does the trick, a Lexicon Alpha.  It connects to the computer via USB, and has L/R line ins, an XLR,  2 line outs, and RCA jacks.  The front panel has an instrument line in, and volume controls.  I did a test with it, connecting my Xenyx 802 L/R outs to the L/R ins, and was able to record mic and guitar on separate tracks.
 
ETA, bought this at Guitar Center in the US for $79.

USB or Universal Serial Bus has been replaced by RS232 communication, and at the same time a lot of situations. USB is now the most widely used interface devices such as printer, mouse, scanner and personal computer. Many people wonder if an easy way to convert the RS232 to USB. Ultimately, they are both serial interfaces.

Thanks for the reply Pete ! I got a Roland UA-25 on the way from e-bay but I'm going to keep your info in mind ! I sold my UA-700 just wasn't doing it for me.
