Analogue to Digital USB unit?

Looking to record LP's to hard drive, but would really like to utilize my current phono pre, a Graham Slee SE 2, as opposed to what I would expect to be a lesser all-in-one unit like the ART Phono Plus USB.

Any ideas appreciated, thanks L'wood
Apogee has a very good AD converter with USB. I don't remember the name. I had an Edirol unit mod'd by the Oade Brothers (check their website). Even though they no longer make the mod, they may also have suggestions.
Benchmark is also coming out with one. I talked to the rep at RMAF and I believe the price will be just under $2k.
