Funny you should ask about Correa - I exchanged emails with Damien today - and will be seeing him and Hector on Monday to get a final fitting for the shoes they are currently making for me.
I think there prices have gone up a bit, but are still a damn good deal for custom made shoes. A pair of penny loafers is going to cost me ARS 450. Or a bit less than USD150.
Some advice - Stop in as soon as you can on Monday. Shoes take time to make and ideally require two fittings (one to make the last, and one several days to a week later to fit the shoe to the foot and essentially fine tune it). Unless you are going to be there for a couple of weeks or know someone coming back to the US in a couple of weeks time (who can bring the shoes back and ship them within the US) you will likely need to leave some extra cash to ship them to the US (which is not cheap - about USD80 last time I did it - plus a later bill from DHL for a few bucks for customs duties and fees).
It is worth it, for both the product and the experience. They are wonderful people.
And if you come back to BsAs you can skip the first fitting since they will have lasts for your feet on file. Just order via email, and go down for the final fitting when you arrive. The shoes will be done a few days later. I think in a pinch you can skip the second fitting but the fit will suffer.
