My two cents…
I was once considering Tom’s distributor. I ultimately got a pertronix system. The lower price of about $100 and extremely easy installation are what sold me on pertronix. Plus, I was able to maintain a factory look with pertronix. Toms price including shipping, was around $250. Is it worth $250? Yes, IMO. it might take a while to sell, but it doesn’t take up much room in your shop. Put it on Market Place too.
