I currently use a medium front Wald basket on my daily commuter. This basket was supported by a Gamoh porteur rack for a few years, so it could handle a lot of weight. I don't recommend this rack for few reasons as I think there are better choices such as the Velo Orange poteur. Since I am carrying less weight, I now use a Nitto Mark's Rack from Rivendell to support the basket.
If your load is light, maybe the Wald basket would suffice. A little heavier a small front rack with the basket. Really heavy load, porteur rack and basket.
Most will tell you carry your stuff on the back of your bike but I like having everything where I can see it and grab it if I have to. Some will argue the front affects the handling and that is true but so does weight on the back of the bike, just in a different way. The question is how much are you going to carry on a typical ride? If it isn't too much then think about using the front. If you are carrying heavy loads, then the rear is the way to go.
