In that case, I would recommend the Singer 4 stitch or the Brother. Since I learned how to sew on a basic Brother machine, I'm kind of partial to them
. If you're using the machine for clothe construction, then make sure the machine comes with a zipper foot. They are so helpful! If you'll be trying your hand at quilting, then I would suggest looking at the manufacture site to make sure you have the option for additional feet, such as the walking foot, quilting foot, and the 1/4 foot.
Also, this is something I've realized with a basic machine. They are great with light to medium weight fabric. If you want to explore with denim or other heavy materials, be prepared to spend a while playing with different tension, needle, and thread. The first time I tried to work with denim, I got a lot of dropped stitches and needles/thread breaking before finding the right combo.
