If you want a good knife that will be a pleasure to use in the kitchen for cooking, buy a Forschner, or two. I have several and they are great tools.
If, in addition, you either: 1. really need to spend a lot of money for whatever reason, 2. have a hangup about having the ultrapremium of whatever you buy (or at least, whatever somebody's marketing material tells you is ultrapremium), 3. want to impress your friends with your mad knife skillz and give them a long dissertation on why this knife is so much better than (etc.), then a quick way to decide would be to go to an online knife store, go to the chef's knife category, and click "Sort by: Price High to Low".
I'm into my hobbies as much as the next cat, but it is really just cooking. Buy something that works to cut up onions...if you want something to wax eloquent about, look into military antique collecting. Of course 100 year old bayonets aren't the greatest for getting that thin, clean dice, anymore.
