Wow! That's actually a set I've been keeping an eye out for several years ever since I saw a picture of one in an old issue of Consumer Reports. Unfortunately, the one in that auction looks like it must have been the super-cheap version with a plain beige cabinet, and the picture looks rather unflattering somehow compared with other pictures I've seen of this model "family"-- I'm pretty sure it's the same basic set though, with the speaker on top and the fold-away carrying handle surrounding the speaker. It's pretty nearby for me, so I'm probably going to bid on it anyway though..! :)
Thanks for the pointer, Bobby!
