UA 5
I've owned this from new, its never been out my home studio and offers superb sound quality. VERY GOOD condition and full working order. Specs below. Just checked tonight and this is still supported to Windows 7 and Mac OS 10.6. Comes ith power supply and install disc but you will need to download the updated drivers.

EDIROL UA-5 24bit 96khz USB audio interface
Two high quality microphone pre-amps with balanced (XLR) and 1/4-inch (TRS) inputs
Switchable phantom power (48 VDC)
Two Line-level analog inputs (-10 dBu) with level control
Two pairs of Line-level analog outputs (RCA and 1/4-inch)
Two A-to-D converters that operate up to 24-Bit data words and 48 KHz sampling rates (full duplex) and 96 KHz (half duplex)
S/PDIF Optical (Toslink) and Coaxial (RCA) Inputs and Outputs (selectable)
and a USB slave interface.
The UA-5 can feed PC- or Mac-compatible computers via its USB interface. (The UA-5 is not designed to be used as a stand-alone mic pre-amp/A-to-D converter; see the M-Audio Duo for that application.)
Phantom Power
The UA-5 provides 48 Volt phantom power to microphones that need it; the phantom power can be switched on or off via a front panel push button when not required. (A single pushbutton controls both channels.)
Zero Latency Monitoring
The UA-5 provides zero-latency monitoring: you can monitor the recorded audio in real-time via its variable level headphone output. The 1/4" headphone jack and level control are on the front panel.
Overload Indicator
The Duo's front panel provides a single Peak LED to indicate when you're feeding either channel too hot a signal.
SCMS
When recording via its analog inputs, the UA-5 acts as a professional device and does not impose SCMS restrictions on its S/PDIF output data stream unless you specifically impose it via your host computer.
When recording via the S/PDIF digital inputs, the UA-5 passes along the SCMS state in the data stream without modification.
Note: The UA-5 is not bit-for-bit accurate in transferring digital data to the computer via its S/PDIF input.
Sample Rate Conversion
The UA-5 offers real-time sample rate conversion in hardware, the only device of its type to do so.
High Impedance Input
The second XLR input can be switched to accept a high impedance input source, like an electric guitar.
