If it's the new Featherweight 75, I own one, and I love the machine. It sewed perfectly right out of the box, and I have had no problems with the tension or anything else about it. It is not my main machine, but I do use it frequently. I think you'll enjoy it!
By the way, don't worry about people saying it doesn't compare to the antique featherweights. That's true in a lot of ways, I suppose. Plus there are lots of antique machine users and collectors on this board who love their old featherweights, but let's face it, they are hard to find and don't have a lot of the features that some of us might want. It certainly doesn't mean there's anything wrong with the new ones, it's just a personal preference.
