i have one of those 2x4 cube shelves from ikea thats almost completely full, so i estimate it would take me months to log everything i have which is why ive never done it.
i like discogs a lot though. whenever i find a new album that id like to own, i always use it to see if there is a US pressing thats in my price range. that usually tells me how much of a chance i have running into it in a store and what i can expect to pay. typically ill expect the store to be selling records $5-10 more than discogs because i know they have to make money and most of the time im fine with that. i do think its a bit tacky when people whip out their phones while theyre digging to compare prices and i know a lot of store owners really hate that.
