My first kitchen knives were a Chicago Cutlery set that was miss place during a move and, really haven't been missed. They were good knives except for the fact they dulled quickly but, they were so soft they sharpened easily

.
I picked up a Trace Rinaldi TTKK in BG-42 several years ago and absolutely love it. It was my only real kitchen knife for a long time has served me very well.
While staying at a motel in Atlanta, Georgia for a period of time, I just couldn't stand using their no name kitchen knives and picked up a Heckels Pro-S Chinese Cleaver and traditional Cleaver. That cleaver was sharp enough to cut ham pretty nicely, better then any of the hotel knives

. That chinese cleaver was something I wanted to try and, to my surprise, it has proven very useful slicing and dicing all sorts of things for salads and soups.
I have a George Tichbourne K3 and K6 kitchen knife models. When they say the K6 will serve 90% of your kitchen needs, they are right. The blade is slightly thick and heavy for cutting delicate things like lettuce and tomatoes but, it has the weight to cut carrorts and potatoes better then the chinese cleaver. Best off all, since they are custom knives, you get them your way. Prices are very reasonable too. Highly recommended.
I recently picked up one of those industrial handled Forschner 9in kitchen/chef's/utilty type knives. For ~$15 it is one heck of a blade. If you are concerned with the sanitary state of your knives, dump that wood handled model and get one of the Forschner plastic handled models (they even make a more expensive model that has some anti-bacterial stuff in it). Big bang for the buck here. I should note that I do not have enough long term usuage here to comment on it in the same degree as the knives above but, knives used by the professional meat packing industry and butchers in general, speak highly of its qualities.
Finally, an often overlooked kitchen knife line SPYDERCO. I do not know if the people who make Global make the Spyderco's as well but, I wouldn't be surprised. As best I can tell, the same steel, same stock thichness, similar edge grind, etc. I have their Santuko and 6 inch Utility knives. Both are performing very well in my kitchen. With their very thin profiles and light weights, they work best on light cutting tasks like lettuce, tomatoes and, similiar items. They are certainly capable of cutting raw potatoes but, their light weight makes you work harder - a heavier knife (more mass) reduces the force required by my arm on these tough guys. Overall a great bang for buck knife, just make sure you compliment them with a heavier duty knife for the touch cuts of meat and such.
