Another review for you here :)
I have tried and tested a number of concealers for a number of different problem areas that I have and I have found a few that work for me. Most of these products are from a drug store so they are very affordable.
Maybelline Fit Me (Shade 20 and 10)
Rimmel Wake Me Up
Maybelline Age Rewind Eye Eraser (Light)
L'Oréal True Match (2 Vanilla)
No7 (Cool Rose)
Mac Pro Longwear (NW20)
MUA Pro Base Prime & Conceal
