Seventy-

Don't worry......Ofna changes the PBS a few months ago to the black head w/ purple cover instead of the purple head. It is the same as the purple head, both are the 8 port. Also they went ahead and put a pull start on the PBS because people were having so many problems getting thru the break in process with the stock starter box. Once you get over 10 or so tanks thru, the stock starter box should be fine if you have some good stick batteries for juice. I have a PBS purchased this summer with the purple head and my buddy just purchased one a couple months ago that came just like yours....aside from the black head and pull start they are identical. You're going to love the PBS.......I know I do.
