I also went to Vass, Buday and Rozsnyai. I was surprised how small the old Vass store is and how little they have on display. Their staff (two middle-aged females in my case) were very friendly.
Of the 3 mentioned makers Rozsnyai's shoes appealed to me the most style-wise. Quality wise Vass looked to have better calf leather than the other two makers. I ended up empty handed, I guess I'm more appreciative of Northampton made shoes.
