Sounds very similar to my position when I did it - I would advise that you step back and have a concrete idea as to HOW SPECIFICALLY having a JD will help you advance. If you can't nail one down, think twice about doing it... will it be nice to have or is there DEFINITELY a benefit to have it? In the end after I passed the bar, I decided that I was not going to take a step back salary-wise and practice law, the JD did not result in a direct tangible career benefit (although it adds some gravitas - but that does not mean $$) - so the question was why do it? I had scholarships and tuition reimbursement through work, so my out-of-pocket was negligible - but the time can never be recouped.
My $0.02, if you are not going to practice law and will pay full price for the JD, do not waste the time and money. Get a MBA or a doctorate in your field if you want to enhance your education.
Don't get a JD as a gap-filler or resume-booster - either have a plan or burning desire to practice law, or think of better uses for your money.
As I am looking at options, I am concerned about the expense of school. Currently I live in the suburbs of DC and am looking at PT programs. Fortunately there are quite a few options, unfortunately many of them are very expensive. As it get closer to making a decision I will have to strongly consider the impact that the cost is going to have on me. I may be in a somewhat unusual position in that I am viewing a law degree as a means of helping me expand a little on my current career path instead of starting a different path. My current salary is in the low 100k range, and I suspect that when I wrap up my Masters and then (possibly) go on for the JD I should be able to move up from here. But I would like to keep the cost of this effort to as manageable of a level as I can.
