Bialetti Musa vs Flair 58

This stainless steel redux of the iconic Bialetti Moka Express brews a delicious cup of espresso in a matter of minutes. It is easy to clean, easy to finesse, and was a crowd favorite among nearly all of our taste testers. It delivers in terms of function but in form as well; this elegant brewer is the most stylish of the ones we tested. Indeed, one of our reviewers loved this brewer so much, it became her go-to coffee maker for daily brewing at home or the campsite

Milk drinks can be prepared by using milk frothers that are also easy to maintain. The quality may not be as good but I think the students will have fun and experience and you don’t have to invest in giant commercial machines and rely on students to maintain and use.

I know Bialetti is "the company" for good espresso percolators but they need to get a handle on their product quality. This is the second one I've purchased (different model) that has had an issue with something falling off after reasonable use. The venus one had the lid come off and this one had the handle come apart from the lid. I can still use the unit but it's nice to be able to open the lid without getting burned

A used one should still fit your budget and those machines are made to last. Pair either with the DF64/G-IOTA grinder and you have yourself a nice little setup.
