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.
I looked at the $35 tool above and the $9.99 one on Harbor Freight (search on 97420) because I need a better one. The 2 tools look the same. Not saying they ARE the same tool but they sure look the same.
