If you want a newer light machine the Janome Gem has proven to be very good. However, you can't go wrong with a Featherweight. I'm a proud owner of 5 (to some that's not very many!) you will really enjoy using the older ones.
I would visit Craig's list in your area that way you can see the machine and hear it (and hopefully make a deal!). I have a White and I was told before I bought one that they would be a little louder than the black ones and they were right. It's not that obvious but the black ones just hummmm! They are so sweet! You will find the perfect one for you-just be patient.
