Replacement distributor

Thanks for the u tube video, love the female computer voice, that could sell anything, LOL! I looked around the net for info on it but did not find that. I thought I read in the FABO thread you posted the link to, that it had an adjustable advance, maybe I'm reading things wrong, pretty much a rookie on ignition systems and timing etc, if you couldn't tell already, just trying to learn since my Valiant has started giving me some grief. I've seen old new stock on these for $150-$200, and from availability I kind of assumed they were discontinued. Discontinued to me would not necessarily mean they are not good but I guess the question would be availability of serviceable parts.
