Scott,
Last thing I heard from a friend, Roland will be releasing a new Multi-track Hard Disk Recorder in the winter NAMM next month. It will fit your budget (or less) and it has everything you’re looking for, plus, it’s this year’s model (Not as old as the AW16). Also, the specs are unbelievable for this price range.
You can make an exception this year and celebrate Christmas one month late and get yourself a gift by the end of January.
