I guess "lease" really isn't the right word. It is more like "share". I have a Siebert 12.5mm standard eyepiece that I am willing to let a needy Astromarter have to use with the proviso that they then pass it on to another Astromarter when they are through with it. I ask only that it be shared. If there are any schools that could use it, I would like to give them first crack at it.
