I used ones for a (IIRC) Cadillac Catera. They were $12-15 each brand new and have a lifetime warranty. I did this a good 5 years ago.
I even did a nice write up that may still be in the archives NOBODY EVER SEARCHES.

I would never use used struts personally!

2000 SVT #674 13.47 @ 102 - All Motor! It was not broke; Yet I fixed it anyway.
