This is a timely question. First of all, good luck with your decision and congratulations on putting yourself in a position to be able to have this option. It's nice to have options.
Tomorrow I have an interview with a company that specializes in Corporate Insurance. If I decided to pursue the opportunity, it could pay very well. However, I've never, EVER considered selling liability insurance to corporate america as something I want to be doing.
That said, I currently work for a large financial services company and 7 years ago I would have NEVER considered working in finance.
With a company like COMCAST, who I also loathe, I would have to speak with someone working there that I trusted to ascertain (that ones for you galen and Quatrarius) what the internal culture is like. If it's a company with shitty customer service for it's customers but is a blast to work for.... well, I might consider it. If it's a company that squashes all of its competitors, but would pay me enough and provide an excellent quality of life for me and my family, then I would consider it. -Not proud of that, but it's me being honest. If I ascertain that the company's benefits outweigh the crappy-ness of their practices. I'm in.
