I wondered if anyone had recommendations for a well priced crimping tool, suitable for use with bootlace crimps?

There seem to be simple versions around, which essentially squash the crimp tube with shaped but fixed formers. And then there are more sophisticated ones, which form the crimp tube into a square or hexagon, using moving formers. Obviously the latter are a lot more expensive, but are they worthwhile? Or for the volume of crimping the typical hobby CNC-er might do, would the basic ones suffice?

Any thoughts or pointers most welcome!

Cheers
