One year my husband bought "me" a shotgun, and I bought "him" a painting. That method works well, too.
One hitch, though, you will need to make sure she uses it on a machine instead of something the kids need or want - we have a tendacy of doing that.
I found a Brother embroidery/sewing machine in Wal Mart in Deming, New Mexico that was about $400 less than what exactly the same machine in San Antonio, Texas. This is what I use for quilting and general sewing. So, you might check around for your pricing.
You are a keeper! It's really sweet that you want to do this for her.
