I have one, kinda like it, kinda don't.. and wouldn't recommend buying it for several reasons:
It's quite expensive - and just look in your local classifieds and you'll see all KINDS of exercise equpiment, including the bowflex. Why? People who get the bug to workout buy the stuff and then end up not using it after a fairly short while. I'd recommend working out at home for free first, make sure you're going to stick with it - you know, pushups, crunches, walk/run, chinups (if you get/have a bar), do yardwork, shovel snow, whatever and notice how long you're staying with it and decide how willing you are to go even further. Decide from there, not just due to new years resolution or whatever, test your desire before spending money.
The setting up isn't horrible by any means, but it does become quite a pain in the butt. If you vary bodyparts during a workout, you'll have to change the stuff virtually every time. Most of the changes are quick and easy - but if you're fired up to work out, you really don't want to kill that intensity of mind by doing little, mundane tasks in between stations. A minute or two is pretty much the average of changing time I think. So like I said, not the worst, but not near ideal either.
It does work and provides a nice workout but consider joining a gym if you need more than a home type, your own body weight type workouts. Firstly, a few years membership at a good gym would be cheaper and better. You'll have greater access to more variety and quality and weight of equipment, be greater motivated by having people in better shape around, and save the money and space bowflex (or any other home gym) would take in your home.
Just my opinion
