Years ago Victor suggested I look into a restaurant supply house near me, and I picked up a six pack of quite functional decanters for $24. I’m still using them for every day purposes, when the nice fancy ones are put away, or are in their display rack.
If you can find any of those kinds of vendors, look into them - good value and tough stuff.
I only properly decant maybe twice a month on the weekends, but at offlines/dinner parties we’ll use 3-6 easily, so its good to have extras.
