I've been using a Husqvarna machine for about 7 or 8 years now and it's been a very dependable little machine. During the first couple years I would only use it for 2-3 projects per year, but since I've started cosplaying, it's definitely been more abused and hasn't shown any drop in performance.
I think the thickest thing I've sewn with it is several layers of denim, and it plugged through those without a problem. I've occasionally had problems where the bobbin has snarled up on me, but I think that was mostly my fault by having wonky tension settings and stuff.
It's not computerized, but it definitely has plenty of stitch options and works well for my needs. I would definitely recommend it to others as a good machine, but I have no idea how much it would cost since I received mine as a gift.
