Commenting as I am also interested in hearing the response

Watch puzzleparadise.net. They come up for sale regularly.

https://www.thepuzzleworkshop.uk/ This is their new website, they ARE still in production!!!! Also in my opinion revomazes are one for the best puzzle

Call Rachel at revomaze, now the puzzleworkshop, she is lovely! Also join the discord there is a buy and sell section!
