A reader asked if he could skip purchasing some of the more expensive parts
A reader asked: “The parts lists are essential resources, thank you for making them available. It would be very helpful for planning purposes if the lists also identified which labs use the less routine and more expensive parts (as you already do in some cases), especially for hobbyists such as myself.”
In response, I added a page to the web site listing the more expensive parts and where they are used. I also discuss which of them you can consider skipping to save some money and which are more important.
