Personally, I just solder the SON spade connectors to the wires and then use heatshrink tubing to provide strain relief. As you note, it's not a well controlled process, but it is better than having a $200 crimper that you only use a dozen times.

I just did some lookin' around, and apparently there are some cheaper ratcheting tools available that might be nicer, found on e-bay. For $20-30, it might just work better than the lousy, but perfectly acceptable job, that I do (on my own bikes!).
