The igniters I hand out at the SCRA launches are Magnelite pyrogen. They sent a free starter set to club reps who responded to a message about availability of a free starter set. It came with the pyrogen mix and a few sets of wires that you could dip.
The logic of the free set is that you will either buy more sets of wires or tell many others about the fine product.
This product is FANTASTIC.
I make my own wire sets and dip them. Different sizes and lengths for the wide variety of Model Rocket motors that I see at our SCRA launches. I use super thin 'wire-wrap' wire with 32 or 34 ga. nichrome for thin igniters and I use 'bell wire' with the same nichrome for larger nozzles. You can even remove the insulation from one bell wire lead to make it smaller.
