All those are great skimmers.
The msx 250 at about $540 is great if you can get one. I've been waiting a couple weeks now, for one and maybe waiting another 3-4 weeks.
The reefflo is also great at about $850, the das at $700 and the bm250 at about $900.
luke33,,you've been experimenting with a couple others, would add those to this list?
