How difficult is it to change the power window regulator in a BMW 3 series? ?

I have a 2003 BMW 325i, and the driver door power window is messing up. From what I've read, I'm assuming that it's the regulator rather than the motor as the window will still go up and down. However, it sticks about halfway up, then it'll slowly creep up after I hit the button again.

I've priced the regulators at about $100 at Autozone, and I'm wondering how difficult it is to "DIY" if I don't want to spend the $200-$300 to have a mechanic change it.

Also, is there an easy way to know if it is actually the regulator and not the motor or a combination of both that is causing this problem?

Thanks!

Oh, FYI, I have very little experience with doing my own maintenance. I've replaced a few parts like oil pumps and starters on older American made cars in the past, but I am definitely not a pro.
