I have Global knives and they are fantastic, but they are very expensive (mine were a gift!). With knives you do pretty much get what you pay for, so get the best you can afford. And get something to sharpen them with and do it regularly. No matter how good the knife, it's useless if it is not sharp.
Before you get Le Creuset - if you mean the cast iron ones, make sure you actually pick them up and see how heavy they are (and imagine getting them out of the oven with the additional weight of food inside). I had a really nice casserole dish of theirs but never used it because I couldn't lift it safely!!
If you have a branch of TKMaxx or Homesense near you, they have very good discounts of quality knives and cookware.
