A few thoughts Kimbalala... you can trust the reviews on Amazon, but only so far, as plenty of those don't understand espresso and what they're happy with might not be what you're aiming for. Read some espresso forums too.
Do your beans have oil on them when they come out of the roaster, or does it take some time for the oil to migrate to the surface of the bean and if so, how long does it take?
I'd shy away from integrated grinders; if that part goes south it ruins the whole machine, it means the manufacturer spent money on that part of the machine which means they skimped somewhere else, and an integrated grinder is always a compromise in terms of its grinding.
Tell your hubby it's going to cost him $1k for the machine and $1k for the grinder. If he says OK then you'll have something worth doing. Years back I sunk lots of money into espresso, lots, and while it does everything I want it to do and does it well, looking back I wish I would've avoided the espresso rabbit hole.
