I'm looking to transfer a bunch of my old cassettes (stereo & multi-track) to digital and want something better than the normal PC input. My preference would be something USB based, so that I can use it with my desktop or laptop. I've tried a Behringer UCA202, but it turns out that it converts everything to mono. I'm currently considering the Edirol UA-4FX as it looks like it will also offer a lot of flexibility for future digital recording. Has anyone else done anything similar and do you have any equipment recommendations? Eric
