Cable Crimping KIT Premium Quality Insulated Bootlace Crimper Crimp LUG 5 Dies | eBay
this is prob best one on ebay
it has longer handle so u don't get sore wrists
trust me when u do 50 crimps in an hour or 2 its good to have a good one
and the dies will do the red blue yellow insulated terminals
and also has a die for the uninsulated brass terminals like u use with the narva white connectors
if u want to go abit more fancy u can always use deutsch connectors
and u can get cheap crimpers for them for around 50 bucks
