Nearly bought one today! Stayed strong, may get it tomos! Lol.
Standard type plenty of black spots, great colour gradient, yellow around the mouth and eyes, it was full of life actually chased down what it thought was food, another good sign, it's beak\teeth were short, the onky thing that out me off was its top lip had a split in it like it had bumped into something, the split was clean with no signs of infection, it wasn't flapping about, didn't look irritated either.
I don't know if I should hold out for a specific type or get a standard one.
