Swing Recommendations

Hi all!  We have an ingenuity swing that my LO loves.  The problem is that we got it second hand and it doesn't work too well.  It rubs on the back and stops rocking.  She is 7 weeks old and probably close to 9lbs so I don't know how long we will be able to use a swing but we want to replace it anyway.  Do you all have any suggestions?  She has a rock and play but seems to like her swing better.
