I am also struggling to find. I prefer glass enclosures and I currently use 3 empty glass coffee bottles (Nescafe gold ones) for 3 of my spiders. The larger one for my P ornata and 2 smaller ones for my 2 P cambridgei.
they seem very happy, but it is hard to clean them because of the small opening when removing the lid. also, not sure how good they are for Avics as they wont have cross ventilation, although it is debatable if this is REALLY required.
Best would be to custom build them, I will do that end of the month when I order my perspex, if I can't find a better (and easier) alternative.
But arboreal enclosures are hard to find for me.
