Avoid 'Birdcage' pianos!
If you see something like the picture on the left, where most of the action is hidden behind a row of vertical metal rods (hence 'birdcage'), you are looking at a Victorian cheap end piano. They are not good pianos and are a nightmare to tune. It is the equivalent of buying an old, beat-up clunker of a car! HOWEVER, if you are looking for a beautiful piece of furniture, some of these old pianos are truly stunning to look at!
