Hi silhouette :o)
I am a beginner at sewing too and bought my first one last year a month or so before christmas. I made some lovely cushion covers which I quilted the front of and having never done it before I must say I did quite a good job and it was fairly easy to do. The machine itself is very easy to use.
This is the one I bought from Woolworths:

Although it says it isn't in stock but it may be worthwhile going into store and enquiring whether they will be getting anymore.
Happy Sewing! :o)
