Buy what you can afford at the start and then upgrade certain things as you go. I like nice ratchets, screw drivers, and a good set of combination wenches. Most other things I buy cheap. I would also recommend making sure you get a set of 6pt sockets. 12's are convenient, but when you get a stubborn fastener that is very tight a 6pt will save you a lot of grief.
I actually like to have multiple tool boxes. I keep hand tools in one box and power tools in another. I have 3 boxes total right now. Also a good idea is to buy those magnetic strips and machine screw them to the side of the box. That way if you are working low or on the ground you can stick the tools you are using to a spot you can reach them from a stool and not have to worry about kicking them around. This is not a bad little box, I have 1 for my hand tools. Also don't forget drawer liners.

This cheap set from lowes is a good base. But you will want to add a full set of metric combination wrenches. Down the road maybe get some more screw drivers.
