I use this one (I forget if it included the correct dies or if I had to buy them separately, but it all came from Jaycar)

I like this crimper, it produces very nice crimps with high repeatability.
My experience has been that choosing a good quality, strong terminal is what leads to good clean repeatable crimps, some of the cheaper terminals made from thinner metal, they bend and deform when crimping.
I buy all my terminals and insulation from RS Components
