I got my A500 for my birthday around April 1991 from the computer section of V&D, a Dutch department store, for the princely sum of 1000 guilders (approx 450 euros).
Then, when we got home I realized I needed an A501 RF modulator (not included) and had to go back and buy one for the rip off price of 100 guilders. I still don't know how my parents managed to afford it back then, but I'm glad they did.
