This is a spin-off from another thread: Currently, the Harley Davidson machine is a huge hit and is commanding some truly high prices. Spin Luck is still popular, although I gather now that it's been out for a while the price is dropping a lot.

What are some machines that used to be really popular when they first came out, and now have dropped to normal prices simply because they've been around for a while? "Classics" as it were.
