REAL, HONEST TO GOD, BARE BONES, WORKABLE CD IGNITION SYSTEM..Good luck, guys, my toroids cost $16 each in lots of 100....Pre drilled circuit boards, 500 at a time, about $.75 each...A few resistors, capacitors, diodes, and SCR and voltage regulator, all bought in quantities of 100 or 1000...Coils from C&H and a box to put the parts in..Ignition wire and a plug cap.....Time to solder the parts in the board...Hall sensors from DigiKey, magnets for the hub.....Never figured out the total cost, maybe I don't want to know...
