Are these units any good I'm looking at the Fostex VF80 with CD-RW. I need some thing that doesn't take up much space and is portable? Are there any better units in this price range? Is there anything I need to be careful of in these units. Can I record on to this unit then burn the 8 tracks or so on to a cd then import them in to sonar or cubase to master them? Thanks in advance.
