Am I crazy for this being my first espresso machine? 🤪

I’ve never used an espresso machine ever (outside an nespresso that had a steam function) but I scored a little discount that made me say “screw it!” Lol.

Now I had a couple of questions - what things should I start buying for it (if any) that would be helpful. Such as different basket/portafilter etc.. any help would be appreciated as I look forward to learning on this classic.
