Dynalite d804ii opinions

I have found what I think is a pretty good deal on two dynalite d804ii packs and three dynalite heads. Any opinions on these older dynalite units? I'm looking to put some lights together for high key portraits and some product photography.

Thanks.

I'm still interested in hearing about other dynalite kit options but the one I was looked my at got scooped up before I got to it.

Well I guess it doesn't matter anymore. I ordered a Paul c buff Einstein light, I'll post my opinions when I get it going.
