Honestly I used mine (which is a Brother) for all my costume stuff. I do regret it just a bit because a bit later I saw a Singer that had a serger foot attachment. But for what I am doing its good.
I think you have to make a list of things you want it to have. Like how many types of stitches, if you want it to have some embroidery to it or a twin needle. Its really what you want to use if for right at this moment. Lets face it there is going to be something out there that will top yours just by a little but you can always save if you want something bigger and better down the road.
