Found this in a local shop a while back for €20, figured it was worth a share.
Allsop Universal Folding Tablet Stand
Could only find one link with a price, but it’s for bulk purchases Computer Supplies Ireland
It’s light, folds down pretty flat for travel, can be adjusted to pretty much any angle you desire, is extremely stable and fits both 7″ AND 10″ tablets, even with a bumper case on. Not much more to say about it, if you find one cheap locally or online, grab it. Actually if you find some online, share the link in the comments.
Will leave you with a few pics, in case you want a closer look.
