Any franchise sort of chain of windshield repair shops should do an ok job of it. Replacing a windshield isn't too big of a deal; it's really just about being careful in cutting it out and laying down the adhesive. (Not that it matters, but I spent a summer many years ago as an assistant at such a shop.)
If it's just a rock chip sort of crack and doesn't have an excessively large star pattern to it, and it's been repaired once already, you might be better off just waiting it out. The windshield is just fine. It may spread someday in a dramatic flash of cracking, but you're not going to be in any additional danger just from a chip/small crack, and there's really nothing you can do to prevent or predict such a random incident. Or it may never get worse. Most of the time it's just not worth replacing until you have dramatically huge cracks. You could replace it now and 2 weeks later get a real crack for some reason. I personally would wait until you really need to spend the money.
But if it bothers you, of course you can spend the money to get it replaced.
The only real crack in a windshield I've personally had started as a rock chip that I got repaired. A few years later at an ATM on a sunny winter day, some melting snow off the ATM canopy dripped a single drop down right on the crack and BAM it spidered out across the bottom of the windshield. Just nothing really that you can do about that stuff.
