If you're buying Henckels knives, just be aware that there are different lines and some are cheap stamped steel while others are forged. You want a FULLY forged steel knife, it holds its edge beautifully and is generally better balanced.
I have a Messermeister Meridian Elite 6" chef knife
that I LOVE. It is forged steel, stays sharp for a long time (but I have a DH who loves to sharpen knives, too). It retails for around $100 CDN ($75 US on cooking.com)and is worth every penny. I find the 6" blade to be the perfect size - I am small, but it's big *enough* to cut pretty much everything. I also have some cheap 8" Victorinox chef knives and they are nowhere near as good.
Basically if you are paying less than about $70 PER KNIFE you are probably not getting a good knife, unless you're buying them from someone's tailgate and they keep looking around shiftily, IYKWIM.
