i looked into purchasing a shtender a couple years ago so i could constantly move around to different areas to study (to make it convenient and to keep from getting tired or bored) such as a podium, shtender, table, chair, school desk-table combination. i actually prefer a very low table and school chair like a elementary school activity table.
i searched the internet and didnt really find anything that wasnt expensive or looked proper, (im facinated by the logistics related to the purchase of antiidolatry items and how to make the purchase given all the different options, it seems impossible given the method of purchasing; but thats another topic)
i saw on kikarhashabat that some use very simple shtenders (couldnt cost more than $15) even some that were hand made using just a couple pieces of wood, i would have attempted making one but it seemed too time consuming and i get depressed when i fail at something so simple so actually i just never got one.
i also looked into those things the muslims use when they sit on the floor to study. it would be convenient to have little study stations everywhere with books already open.
