Panning Machines and Specialty Equipment... oh my!

Still can't figure out why panning attachments for Kitchen-aid mixers are so expensive. Here's an example of the excessive cost that happens when you put a stainless steel element into the equation or you put a brand name on it that associates it with creating specialty foods. I've been baffled at the low cost of motors used in tempering machines before, but this piece of equipment puts it all into perspective. Keep in mind, the mixer is not part of the price - it's sold separately. This is just the "attachment" price.
If you can't quite make out the price for each of these, the top one is $699.99 and the bottom one is $599.99! One works with a table-top mixer and the other is a concrete mixer!
