What is the best quality coils out there? 

Stewmac has coils but they were too expensive, so I took a ride with cheap alternatives and was not disappointed.

My findings are that coils made by Electriksola and Adept are very quality coils and cheap in the one figure range. 4oz of 42awg will get you around 4 single coil pickups.  Coils by Temco tend to snap a lot and knot up.
