Anyone half a smaller sized Sewing machine they love?

I work nights with Hospice clients, LONG shifts, lot's of down time, I would like to buy a smaller sewing machine that sews using regular stitches, but one that is easier to carry than a full sized one. Does anyone here own a machine like that? Something easy to carry that can do a straight and zig-zag stitch that compares sewing quality-wise with a full sized machine? I do not want a toy... I also do not want to lug around a full sized machine. Any input on a machine that might give me quality stitching plus some increased portability via a smaller machine would be greatly appreciated.
