hi forum, i'm following a few espresso machines on ebay (ex cafe, restaurant etc), but cant seem to get a definite answer from vendors regarding specs.
i basically want a machine that can switch on in the morning via a plug timer, (15amp max @220v unless i can find 20+ amp socket timer) so i guess it must have full manual switching for the boiler element.
ability to controll pressure and temp would be important, as i know i want 8 bars at 90 degrees for 30 seconds as that is what my favourite coffee bar have their staff do via their huge and expensive italian job.
is it asking too much to find a machine that can get close to what theirs can do. i'd be buying their grinds which they sell also.

Welcome to the board.
Any machine with a vacuum breaker will have no problem with a timer and nearly every machine that is commercial that I know of has one. There is one machine in the ProSumer class that requires it's own timer but you are not looking at them.
Pressure is adjustable on all commercial machines but you need to take the covers off and have test equipment to accurately set pressure. You could use the on machine gauge but it might be off calibration.
Temp is adjustable also on all commercial machines but depending on design (HX or DB) the method of adjustment differs but you will likely still need to get inside the machine.
The good news is that most all machines you will get used are already set correctly unless someone goes inside and mucks things up.
NOW, MUCH MORE IMPORTANT THAN ANYTHING ABOVE, YOU NEED TO BUY A GOOD GRINDER THAT IS ABLE TO GRIND FOR ESPRESSO, YOU CAN NOT BUY PRE GROUND COFFEE FOR ESPRESSO!!!!!!!!!!
The grinder needs to be adjusted for your exact machine and all the components on it which will be completely different than the machine in your fav coffee shop. In addition, the grind requirements change from day to day as the coffee ages so even if you were increadibly lucky and the shop just hapened to get the grind right for you TODAY, tomorrow it will be wrong.
ADD to that, ground coffee goes stale in about 15 minutes from the time it is ground, you can NOT buy pre ground coffee for espresso. Also, Roasted beans are stale in about 2 weeks FROM THE DAY THEY ARE ROASTED ON, you can only use FRESH coffee for espresso.
