Hi, i think there's nothing wrong with having two different tools, that produce similar results in completely different ways and with differences in quality achieved.
I have an espresso machine mainly for my own enjoyment and a drip machine for guests. Sometimes I'll drink a cup from the drip machine when a guest is around I'm feeling like it.
Kids will grow up faster than you expect and with that comes a little bit alone time for the parents here and there. You may enjoy the fancier option than a lot. If not, you could sell it then?
