I bought a new one from Snyder's (original style). It IS remarkable for the money. However, be advised- the wire between the lower plate and points wasn't the super flexible type it is supposed to be! Other than that, and the points cam needing to be polished before use, it was spot on.
The rebuilt distributor I bought from Bratton's did have the proper flexible wire already installed, but the points cam also needed to be polished before use.
