There are many good "used" modern pieces from the 80's and 90's available out there. Many furniture manufactures in the last 20 years have been through changes, downsizes, buy-outs ect.... But, to see products that are affordable and a possible good fit into today's contemporary or modern environments I suggest looking at an ebay seller like midcenturyguy
out of Houston.
At this seller's site you can see Eames, Herman Miller, Knoll and other "classics" but, you can also, see some items from the 80's and 90's worth a "second look". I checked and saw pieces from Metro, Vecta, Kagan, Brayton. Stow Davis, Helikon, B & B Italia, Mueller, Dakota Jackson, Dunbar Thayer Coggin and yes Gunlocke.
Gunlocke is a wonderful old 100 year old+ American Company and everybody has seen and sat in their famous "Courthouse" chair. Wood chairs were what the company was practically built on and numerous knock-offs and variations of the Court House chair are still to be found. I even think at one time I saw it or a look-a-like sold in DWR.
Anyway, whether furniture or an important lighting manufactures like Artimede there are some good items produced in the last 20 years worth buying, refurbishing and
using and I'm delighted with sellers like the ebay seller midcenturyguy and locale stores like Phoenix Metro Retro and Red for making these pieces available for purchase!
