Screw the lever/non-lever debate . . . BOTH work, and that's all that's important!
EVERY machine has a learning curve, in that no machine is so (a) completely forgiving, so (b) operator non-dependent, that you make (c) phenomenal espresso right out of the box! Even super-autos, which may have (a) and (b) down, but they sure as heck don't lead to (c)!

First, what's an "Alexa"? There is an "Alex" (Izzo Alex, and Izzo Alex Duetto II); then there's an "Alexia" (Quick Mill Alexia), and an "Anita" (Quick Mill Anita). Based upon the price, I am presuming you meant the Alexia -- but I just want to be sure . . .
Secondly, not all US-based vendors ship into Canada, so -- if you're looking across the border, take a moment to double-check availability. (There are also potential Customs & Excise issues to be aware of.)
If all you are going to make is espresso -- never steam milk, and never for company (i.e.: max. 2 cups at any given time) -- I'd go for a lever machine. From among the three brans you cite, I'd look at the Ponte Vecchio (if available).
Cheers,
