In general you can tell it is a good crimp by the wire breaking before it pulls out. At a more practical level, just give the wire a good tug after crimping to verify it was a good crimp.

Now you can buy the ratcheting crimp tools for about $35, which makes them reasonable for home use. http://www.hamcq.com/tools/crimping-.../prod_273.html
These tools work much better than the simple plier type tools.
So we've gone from trying to help a guy with a small shop project to building space ships


You don't NEED a $35 crimp tool to make good crimps.

After you crimp it tug the wire to make sure its secure.

The more expensive tools make it harder to screw it up, and for some specialized connectors/terminals are the only way to crimp them.
