Are these hard to come by? I just picked one up at a consignment shop this past Saturday. It sure is nice to look at, but shaves just the same as my Black Beauty 
I believe the gold Super-Adjustable comes only 1969.
I don't know that it would be considered very rare. As they have may only made them for one quarter and or year, I would bet to say they made more of these than they did double rings in a quarter. I see them around for $10-20 where I'm at.
They're nice to have especially if you get caught in a "must have adjustables" warp.
Wow, the few I've seen on fleabay went for $50 and up.Is the reason I don't have one yet, I can't justify paying that much for one. If you encounter a decent shape P1 model, I'll happily pay you double your $10-$20 cost for it. lol
Damn, the only 2 I spotted still open for bid were ones in the $50+ range. *sigh* figures, just my luck... lol
It's always hit or miss on there, but I"ll keep my eye open for ones out here.
