What color are you trying to correct? I actually think Maybelline Age-rewind and Loreal True Match concealers are pretty good. I don't spend too much on concealers, because I am not trying to draw attention to that part of my make up.
I also think the MAC Studio Finish concealer is pretty good, it creases a little on me, but I am NC15 and that one works. It comes in NC20 as well...
I have been using the yellow correcting primer from this collection for about 2 weeks. It doesn't really hold up in my T-zone oil patch of doom, but it works well as a primer around the eye area that gives me SPF 35 and no eye irritation. So, while I did not love it for a correcting primer, I did find a great use for it.
