I have a lot of cufflinks as they have been on my regular thrift store circuit for a long time and I have gotten a few as gifts. Some favorites are my Pound/Dollar sign sterling ones from Links of London, and some antique/vintage enameled small octagonal ones that cost $3 at a thrift store but are probably worth quite a bit. I wear them whenever I can but I don't wear suits or even jackets around so my better shirts don't get used that much. I really don't see wearing contrast collar/cuff shirts without a suit, either. I don't really know the brands and I don't worry about it. All new stuff like that is IMO too expensive, at least for my budget. I found a bunch at Thomas Pink, Ben Silver and Charles Tyrwhitt (all online) that I like though.
