I would not buy it with so many used enlargers and lenses of that class available for few Euros. Unless you live extremely rural I do not see why there should be that much difference in availability in Portugal (and I take into account the lesser incomes there in the 60's to 80's).
Have you considered acquiring a used one?
Yeah I leave in a preety remote area in the north, all the used ones I saw were only passed hand to hand in the capital region... I saw this one kinda cheap and not to complex to start. And with analogic cameras I only work with black and white.
See the german description of it by Fotoimpex and have it translated, it is more telling than their english one.
It seems to me the enlarger corpus can be tilted by 90° for larger projections against a wall.
As a benefit over most used ones I consider that it goes up to 6x6cm in format.
One dealer states that also floor-projection would be possible. But from what i see one would have to take off the foot of the collumn and mount it facing backwards, which, if possible, would be a bit more hassle.
