I know a few things about European locks, but I'm not so well informed about US locks.
So I would ask for your advice and suggestions on which locks should I try to get/be on the lookout for for my collection.
Thank you very much for your help

So as of now I have a:
[see picture]
Corbin padlock
American 5200 padlock
Another American padlock
Junkunk american padlock
A schlage
2 Kwicksets
2 medeco biaxials
A kwickset smartkey and a corbin emhart is on their way to me


Master lock are not included because those are readily available here so they are not interesting from the collection viewpoint.
Here's my list of US locks which I would like to have in my collection on the long term:
As I mentioned I'm looking for your opinion on amending/supplementing the list

Schlage everest
Sargent Keso
Medeco Air padlock
S&G padlocks (8088, enviromental, 961)
Some SFIC cores
As for quality: are Schlage better quality than kwicksets? Or is it the other way around?
