Run a long extension cord to the curb for your kids and let them set up an Espresso stand. Its the newest thing and then they can compete with Starbucks and Mickey Dees. Lemonade is so out of vogue these days.
I have had this exact machine for 16 months and use it just about everyday. It is a great home use espresso machine.
I paid $169 for mine and have no regrets.
The stainless stays clean, the valves and pumps are good and still working after over a year, no leaks anywhere.
You have to purge a little water from steam tube before frothing milk but it takes about 10 seconds and you can do it right into the drip tray.
I think that with this machine as well as a good burr grinder, I am able to make just as good coffee as the local coffee stand.
