While I don’t have any firsthand experience with the Revo, I’ve
heard nothing but good things about it (except perhaps for some
grumbling about its price). Some technical specifications are here
for the Revo 540B:

I do own a Roland MDX-40; the “big brother” of the JWX-10 which is
intended mainly for jewelers, and I’ve been very impressed with its
accuracy and ease of use. It is essentially the same machine as the
jeweler’s mill, but larger. The JWX-10, with travels of 140mm (X),
105mm (Y) and 105 mm (Z) is somewhat smaller than the Revo at 172mm
(X) 110mm (Y) and 200mm (Z); the MDX-40 is larger (305mm x 305mm),
except in the Z dimension (105mm). Like the Revo, both these
machines are run with stepper motors, and they both use linear ball
slides for motion. The Revo uses ballscrews to move the axes; the
Rolands use acme screws. The spindle speeds are a little slower in
the Roland machines; the MDX-40 goes at 15,000 RPM; the JWX-10 goes
20,000 RPM, while the Revo spins at 25,000 RPM. (Higher spindle
speeds allow faster feedrates with very small cutters.) However the
Roland machines can actually run considerably faster than the Revo:
3,000 mm/min vs. 1,200 mm/min. Both machines come with a 4th axis as
standard equipment. The Revo is considerably heavier, at 180 lbs to
the JWX-10’s 88 lbs. The Revo is pictured with a mist-coolant
system; although I’m not sure if it’s an optional extra or included
in the base price; the Roland doesn’t have that (although one could
be added). The JWX-10, like the MDX-40 comes with an automatic
tool-height sensor, which I’ve found extremely helpful for zeroing
very small-diameter tools, which are quite fragile. The Revo doesn’t
seem to provide anything like that. The Roland machines also double
as high-resolution scanners, with the addition of their (optional)
piezo-electric probes. I didn’t see any mention of a scanning
function for the Revo. The Roland machines also include a CAM
program that can derive 4-axis toolpaths for milling from ones 3d
designs. I’m not sure if CAM software is included with the Revo, or
is extra.
