Really helpful. Especially since you give access to the raw data and I can input energy costs in my area as well as a sale price for a specific drive and see the updated results live and make an informed decision.
The next step would be to create a script to scrape a few dozen ecommerce sites with all the relevant model numbers and have the sheet get updated in near realtime... (Please don't ask me for help,, I'm a big talker.. I mean thinker.. but that would be beyond me).
