Discogs says I have close to 3800 LP's on my shelves (I have a decent CD presence as well that I do not track on the platform). While most purchases in the last 20 years have been primarily Jazz, I still have the Wave / Punk / Rock LP's I purchased in high school, college and earlier adulthood.
I am still an avid collector and frequent record stores, record shows, antique shops, flea markets, etc... My August trip to NYC was particularly fruitful, as have my regular visits to Chicago. With that said, a good chunk of my recent buys have been better condition "upgrade" copies for titles I already own. I flip the lesser condition dupes locally to help foot the bill. As far as new vs used, I primarily buy used on the "collectible" side, what ever that means anymore, but will pick up new reissues and new music as the mood strikes.
I regularly post new acquisition's or just what's on the table on Instagram to support discogs data, ostensibly for insurance purposes but also to share with like minded friends and folks on that platform. Feel free to take a look here: https://www.instagram.com/cuyahogabirdie/ I welcome comments, feedback, commiseration for lost LP's, ridicule for the time, funds, and space dedicated to this habit / hobby, etc...
