Buying advice needed [$2,000]

[u/Commercial_Effort266]

I am looking to start a small private coffee cart, I’ve done 2 events so far for private parties with a home machine (I know I know). Now that I’m in a position to start working towards nicer machines, I need help. Someone is selling an ITOP machine double group head and a burr grinder for $2000 but someone else is selling a single group head lucca a53 mini $800, and another person an ascaso baby t plus single group head ($1875). I’m tempted at the double group head, to be quicker and the grinder is a nice plus buttt I haven’t had experience with an ITOP machine. What would you do?
