Subject: Torn between new Domobar Junior or used 2 group commercial..
 

I have narrowed my option (in New Zealand so selection is limited) to a Domobar Junior for around 2,450 NZ or the other option of going for a used 2 group commercial machine for around $2500.  Seeking any advice here.  I like the idea of the commercial machine being plumbed, very temp stable, and having a rotary pump.  However if I go commercial i would likely cut the machine on in the morning and turn it off around 2pm so I am unsure if the repeated on/off day after day will cause any issues?  Thanks for any advice!

I can't see any reason turning it on and off will cause any problems. I have run my machine on for 24/7 and on a timer, just for a few hours in the morning. There are issues either way. Leaving it on is harder on the rubber parts and turning on and off causes more heat cycles on the joints and electronics. Pick your own way.

My PERSONAL bias is to the commercial machine, providing that you have the room to set it up. Don't forget though, you will need a good grinder to go with either machine. You could look at the B Vario or a used Mazzer
Super Jolly at a price of about $400 U.S. Any less of a grinder and you won't do either machine justice.

Just keep in mind that if you go with the commercial option
you should give yourself plenty of warming up time IF you want to turn it off every afternoon
why not leaving it on all day?
warming up time
any 2 gr out there will have
a boiler with AT LEAST 6 liter and 2500w and up ( 9 liters and 3500w more common)
so more then 1 hour will be needed for temp stability to the group

That is a pretty normal warm up time for a lot of us here anyway. I know my single group is on an hour before I wake up and it is half an hour after that before I make coffee, so I have a 1 1/2 warm up. ... when running on a timer. I go back and forth, sometimes it is on nonstop other times I use a timer, it just depends on my "mood" lol!

I would get the commercial 2 group so long as you're sure it fits into your budget. Make sure everything works that you expect to work.

The only true concern here is the unknown condition of any "used" machine.

If you cannot afford to repair, replace parts or clean up a used machine in addition to the original purchase price, then new is your only option.

If you are depending on used equipment to be in perfect condition, I would call that a gamble at best and a nightmare at worst. (Edit: It's important to note that this applies only to machines of unknown origin. NOT machines from the B/S/T forum here or refurbs from manufacturers or authorized repair centers.)

Good Luck,
-James

Thanks for the info guys!  My current system is a B Vario (which i love!) and a PID'd Silvia.  I have a love/hate relationship with the Silvia.  It is capable of great shots but I am sick of all the fiddling around required since I primarily make milk drinks.  The steam on the Silvia is in the not quite adequate to barely adequate range.. then after steaming you have to refill the boiler, etc.  I am leaning towards a commercial rig.  It will probably take me a few weeks before a good buy shows up on the used market.  I am a little concerned over some machines having nickel plated boilers, nickel is highly toxic to humans iirc.. and over time these boilers show that the nickel has worn off... so um.. where did it go?  Yeah, I guess in the cup.  I guess copper isn't much better but oh well, I gotta have my espresso.  I have seen some steel boiler systems but nickel is also used in SS so not sure the implications there either.  The new Breville dual boiler coming out is interesting but it just doesn't look capable of lasting many years imo.  I suspect the first thing to go will be it's computer and LCD, it also seemed to rely on a lot of plastic tubing.  Anyway, I'll let you guys know what I find and might still need some advice on what I do see.

Several of the used machines I have seen listed state they have had full services with paperwork before the sale (usually by one of the two well known service centres here).  I will try to go with one that has been well looked after and recently serviced.
