I did order them, curious if they were worthwhile or not (plus trying to find out why my Stack and Tilt has fallen apart in the last 2 weeks after being so good for 8 months) - I found a number on the Medicus site to call, it took them a while to figure out where my order was, but as soon as I told them what the product was the customer service rep said that they'd had several thousand of the CD sets in the initial run and sold out of them almost immediately, had no word on when their next run was set to be delivered. I left my order on backorder rather than cancel, but I'm not too confident in their system actually delivering since he couldn't find it in the computer. I also wondered about his statement about "several thousand" - that seems like a lot to have gone through so quickly. My personal thought is they had a very small run to see if there was any response and now they're trying to line up a larger manufacturer to produce for a lower price to them.
