As you know, the Armour 1:100 line has been pretty much defunct for a few years now, with the explosion of competition it's really lost mindshare, which is probably why there isn't much talk about it.
(Skysurfer just posted about his 1:100 CDC stuff the other day -- it happens :-) )
I used to collect this line, it's what really got me into the hobby -- you can see my collection here.

The F-4, F-14, F-15, Tornado, and F-18s I think were really good particularly for the time... (the F-4 Mig Killer was the first piece of diecast I got with a real "wow" factor -- still really dig that model). Most of the WW II stuff, not so much IMHO -- the P-51 is particularly poor I think. I don't have any of the helicopters but they looked pretty nice. Same with teh F-5 and Skyhawks, which also look good -- and seem to command the higher prices on ebay.
"Back in the day" these were $20-$35 a pop, so when 1:72 stuff started saturating the hobby shops for the same prices and better quality (CDC's QC was all over the map -- I got a Harrier that looked like it was glued together by an uncoordinated monkey
) it kind of pushed CDC's 1:100 off the shelves.
Now you can get 'em for $10+ aftermarket, but that wasn't always the case.
I haven't seen the few FM 1:100 releases myself to comment on those.
I haven't had my 1:100 collection out on display for some time, but I can't bring myself to sell 'em off either...
