Supplement books

[J6A]

So lately my bathroom recreational reading has been the many supplement books I own.  I'd really like to start playing some of them.  Right now I'm playing some Saipan, then I think I'm going to jump into First Axis.  After that, probably White Eagles.  As I read them, I realize that the earlier ones which used 4 - 6 games to play some scenarios,  aren't quite as bad as they seem.  Some just use 1 or 2 counters from another game.  While that's a pain, it's not the end of the world.  Right now I'm reading through Secret Weapons, and realizing its likely to be one I never play, or at least its way down on the back burner.  Too many different games needed, too many special rules, mostly really big scenarios.  If I had a regular FtF opponent, that would be one thing.  For solo, I like smaller, quicker scenarios so the game doesn't always dominate the table.  That being said, I'm loath to get rid of it because it might bug my completist nature.

That being said, if I was to dump some PG stuff from a practicality standpoint, it might be some of the older supplements.  And possibly Guadalcanal/Jungle Fighting, as they are very low on my play list right now and I think Saipan really shows an advancement in the series.  That being said, once my fictitious rich uncle dies and leaves me $100 million and I can play games all day, I might get around to it.

Okay, enough rambling.  Which of these supplements books have you enjoyed, which have you thought "Ugh, that's $25 I could have spent on something else"?
