just price for bracket?
hows it install 10 minutes?
 no drilling?
We prefer to sell with the coils.  Finding reliable, used coils turned into more of a challenge as they seem to be hit and miss.  I've also got a fair number of the wrong coil, and have received some that were the correct unit but failed.  The boots are normally in pretty bad shape with used as well.  We believe that the value you get with the new coils, boots, and a warranty make it the best option.  PM me if you have more questions.
As far as the install time, it should not take more than 10 minutes and requires no drilling.  All you need is a few simple hand tools and the kit includes instructions with diagrams and photographs.
