When you say "very undesireable," do you mean in comparison to newer/better mechanisms, or simply unplayable..?
Both Bastari and Stagi made/make concertinas with various action designs. One of the poorest action designs is that the buttons have an aluminum blade sticking out of the other end of it which has a rectangular "window" in them through which the lever pokes through. There's a lot of gap between the window and lever - and - there is nothing to keep the button (with it's windowed blade) from moving forward/back along the lever... *
except* for a small bit of plastic tubing.
This tubing is installed over the blade between the lever and the underside of the button. It acts as a cushion to keep the play minimal and to keep the button blade end from wandering up and down the lever. In reality the buttons wander anyway, and when they do the action binds. The tubing also degrades rapidly and needs to be replaced periodically (better with something like neoprene which lasts far longer).
I was just looking at the site again and now realize that I can click through to some close-up photos - in which the buttons appear pretty uniform so either they adjusted them to appear pretty for the photo or that box has a better action mechanism.

I have a Stagi 30-b and find the action a bit stiff. I thought maybe this would be an upgrade from that--considering the price.
All Stagis anglos have fairly stiff and ununiform action. It can be made somewhat better with tweaking the spring forces but that's not going to help with thier asymmetrical lever arm design/construction causes the action to wear out quickly (aluminum against aluminum - what were they thinking?).
Still, that Elderly box appears to be reasonably intact and the price is very good - but depending on the model you have, the Elderly box may not be any easier to play (probably be larger and heavier as well given that it has 1/3 more reeds).
