I use an Apogee Ensemble but that might be out of your price range and you may not need what it provides is a great clock and outstanding A/D converters. I use a hardware mixer that I use to monitor that I’m really use to so the Apogee fit my needs. But If I didn’t already have a mixer I would look to UAD.
I think if I was starting out I would look to a UAD Apollo because you can use their plugins on the way in. That is important if you don’t have a lot of nice high end pre amps like Avalon or Neve. Their plugins are really outstanding.
