Since January I was looking for a buttoned RS1. They're pretty scattershot in terms how often they pop up and how much is wanted for them. Here on head-fi they've been going for about $425 with or without the box. If it has the box it sells in the first day. Ebay is a whole different animal. There was a claimed NOS Buttoned RS1 from about '06 went for $900! I saw an auction complete with box and paperwork go to $550. I decided then that was my benchmark for a complete package. I lucked out one day on ebay and got for about the same price and in the first hour it was listed.
Regarding a buttoned RS2, those are more of a needle in a haystack. I saw one here on head-fi complete with the box go for $200, it was later flipped here for $275. Canuck Audio Mart had one with the box close to $300, I remember @ruthieandjohn really wanted to hear one so I forwarded the listing to him. The only ebay action is the one up right now going for $325 without the box.
It's a tough market out there for vintage headphones.
Yep, i bought that RS2, thanks to @krud484
