I like espressos (especially mochas) but they take a bit of work to prepare a single cup. With drip brew, I can do very little and get unhealthy amounts of caffeination into my corpse. Also, I pour ungodly amounts of creamer into my coffee. That Mason jar is quite literally half coffee half creamer.
That as well will go on my list for prospects, although, I think it’s going to go closer to the espresso machine area of the listing! you are quite right they are a tad pricey up front lol
