I purchased the crimper you hit with a hammer and a heat shrink splice kit from Genuinedealz , thinking I would never use it again and didn't want to shell out $250 for a crimper. Ironically, I used it again within two months. Worked great both times. They have the expensive ones as well if you want to go that route. Free shipping and a great source for wiring supplies that I found on this forum. They will also fabricate custom cables for you.
