We need to buy a secondhand iClicker and textbooks for each class, but we have to share the lab's $2000 oscilloscope when a personal one costs just $200. Another point of owning our instruments is that we can grow into it. Even after a semester of lab classes, the oscilloscopes, spectrum analyzers still feel foreign to me.
