I would make a copy of the profile before making any changes as the ability to "revert to original" still has not been implemented by JB

Any of the commercial machines will take much longer than 15 minutes to warm up. All those you listed should have no problem with back-to-back shots at the rate an amateur barista can turn them out. With the possible exception of the VAPE1, you probably should let any of those warm up for 30-45 minu...

Bringing a machine to the US also has complications with needing to change to 120 V operation and ideally getting safety approvals. The CE approvals don't transfer to US approvals. Unless there is sufficient volume to justify the upfront expenses, it doesn't make economic sense to import "yet anothe...

Edit: The suggestion to reach out to Chris' Coffee only makes sense if you are in the US. I would reach out to Chris' Coffee if you are genuinely interested. I believe they are the presumptive importers if either were to be brought into the US. The discussions I've had with them over the years have ...

I pull out my decades old "58" from time to time, just to confirm that it ain't the tamper but the hand that is guiding it that is likely the problem. Or it is just poorly designed and executed tampers that have misleading marketing, suggesting that they are "calibrated". Yet another reason marketer...

Welcome to H-B! What grinder are you using? I'm going to make suggestions based on something with traditional burrs. Your soak times seem exceptionally long to me. At least as I think of it, the soak is primarily to evenly wet the coffee so that the puck has better integrity. While the grind you wil...

Ike's approach works for Ike's selections of coffee and expectations from that coffee. If you have different coffees or expectations, you may need something a bit more controlled. 20-30 seconds might be appropriate for a "dragon", but shorter flushes are generally more appropriate. I typically would...

La Marzocco Micra - Top-quality shots - Very forgiving - Ready to use in under 10 minutes

I've only used the Moonshine 64 mm Mizen, not the media-blasted ones. I'd put the ones I have in roughly the same category as the 64 MPs in this context

Budget? Preferences in espresso? How long are you willing to wait from deciding you want an espresso to being able to pull one? Otherwise you'll find a three-group La Marzocco as one of the best choices
