Diamond jigs are probabally the most used Jig I own. Ive bought from lots of places.
I however, dont by the cheapest.... you can probabally get those at a Academey store pretty cheap. The chrome comes off real quick, and you HAVE TO change the split ring and hook since they are POS....
heres some ideas
Personally I like Hammereds over just the normal silver or gold. but thats a personal preference.
On most, I make my own assist hooks, but, thats a personal preference also. If you do that- my thinking is-- I know what the strenght and quality of the cord is and I put my own hook of choice on there. But, thats just me. Most folks dont go to the trouble and want it ready to go.
so back to your question of where and price.
These are just opinions
heres where I and others wrote about'm in 2013 and others chimmed in.
Ive also bought some of Kils gold ones this year and simply put a assist on the bottom of the jig..
let us know what works out for ya...
