Which strut assembly would be better?

Monroe is fine but hold on a minute. This job is a bit time consuming for the home mechanic and when you're done you are also going to need an alignment done as well. Here's my suggestion. A lot of shops advertise buy 3 get the 4th free or they throw in a free alignment. Shop around, bargin with them and realise the true price of doing it yourself. You may not save all that much. Also I'm wondering why you are changing all 4 struts. These rarely go bad on Saturns so it seems very unusual. You sure this is somthing your car needs. I'm very skeptical.
