Coffee machine recommendations for office

We are a team of 20 looking to get a coffee machine for our new office in HSR. Already tried - Cothas (didn't like it), CCD (was okay but too milky at times).

Please suggest some good options along with their cost / link to buy. Someone recommended Budan coffee machine so if anyone has tried it let me know. Also, do mention if you have any sources to rent coffee machines before buying them.

Thanks!
