I have a F1220A, which is basically a lower power version of the 1320 (from what I can tell). I use it as a vocal monitor. I think it's great. I used to have a monitor that ran off of the PA. It had everyone's vocal in it and I had to try to pick mine out. Now I'm the only voice coming out of it and I control the volume. It also has a feedback filter that works pretty well.
I have one. It's still new in the box cuz I havent needed to use it yet. I did a fair amount of research and this one rose to the top for bang for the buck and like that it can reasonably perform as the main PA for vocals for an acoustic gig or as an mp3 jukebox for family backyard parties/BBQs/etc.
