There are two types of injectors disc & pintle (I think thats right), read up on the differences, you should find that most aftermarket are disc. As for being under $300....well then there ya go, $329 is the cheapest you can get them, that is your base price & then you have others that charge more or less for them. There are also other options...flow matched or non flow matched.
For instance about valve springs....sure there are half a dozen or more companies that sell them, however, I will say that there are really only a few that physically manufacture the spring....everyone else just re-sells them.
