I am presuming you're looking at

versus

Both are "commercial-worthy" machines, to the best of my knowledge
*. Both are
approximately the same price ($8,300-$8,600); both have three groups, two steam wands, and a hot water tap. But . . .
The Rancilio has a larger boiler (15L v. 11L), and a higher wattage (6000W @ 230v v. 5700W @ 240v). In terms of
size, the Faema is 37.6" W x 21.3" D x 26.5" H, while the Rancilio is 38" W x 20" D x 19" H (which will increase with the foot extensions for true commercial use).
I should
think, Joseph, you need to look at 1) ease of service where your coffee shop will be located -- after all, you
will need service; and 2) the overall look/appearance of your store -- in other words, the Faema Legend is a classic machine, and definitely has a "retro" feel to it, while the Rancilio is all sleek and modern. Which fits your decor best?
Cheers,
Jason
* I need to make clear, my
direct experience is limited -- while I have been lucky enough to pull a couple of shots on a Faema Legend, my reference point here is
strictly as a consumer: I've had numerous shots from each, and both can "keep up" with the demands of a cafe from what I've seen. Hopefully someone with more "hands-on" experience will also chime in.
