I have two 160 WS and one 110 WS that I bought off of eBay as a kit. It was 299.00 for the kit which included softbox, umbrellas, IR triggering device for the strobes, sync cord, stands (3)for stobes, backdrops, barndoors W/ filters. It was a nice setup for the price. I also have 1000 and a 500 W tungsten set up with softboxes that I got from Amvona on eBay. I bought the backdrop stands (three rail system) from them and I have about 9 backdrops.
Hope this helps.
Here is the item # 360074164991.
The rating is 180 ws now. Hope this helps. ed
