You know, I like looking at the girls, but I don't know if I buy more stuff from companies that feature spokesmodels like Chelsea. Mostly I buy stuff from companies I trust, like Planet, Freeflow, Crossfire, Dye, JT, PMI, Evolve, Ti, etc. I get stuff from websites that have big selections at reasonable prices. Some of those companies utilize cheesecake marketing, but most don't.
I guess when I want to look at women, I look for women, and when I want to look at paintball gear, I look for that. I don't find it offensive, but I don't think it affects my buying habits.
