I started out with a really cheap set, because that's all I could afford at the time. Over the years the stuff that gets a lot of use eventually broke & I got good stuff. Craftsman, SnapOn, whatever... I still have some oddball sizes of the cheap set.
But I think in the long run I spent more money that way. I would have spent less if I'd got a complete set of good stuff instead of 1 socket at a time. It's your money - only you know how much you can afford right now.
