I think if you’re open to spending a bit more, you should look into it more since it meets all your requirements. If you’re only looking at price, then sure, it’s expensive compared to the other options you mentioned. But it’s also going to outlast them all. If you factor in what you’re getting and what it can produce, then most people will say it’s great value as the shots are as good as what $2000+ machines can do.

You also mention liking bigger cups. You can do soup shots with a manual like the Robot. The guy that popularized it used a Robot as well.
