Any one of the machines you listed would be just right for your current needs. It would also be a great back up machine for later when you decide to venture into quilting. I have and love the Janome 3160, it is my travel machine although I do set it up in my living room in a sweat shop style of stitching and have pieced a quilt on it. It has been reliable, easy to use, and have had no problems with it.
One thing you might consider is the availability of a dealer near you. If you can find any of these machine at a local dealer, that would be a good way to go in case you have problems later. I can only speak for the Janome but mine has only been cleaned and never had a repair (it is 6 years old) but something to consider.
Good luck in which ever you choose and welcome to the forum. You can learn lots here!!
