I have casually wanted one of these just to kick around and use. I missed out when they were released. I found this one on eBay: http://www.ebay.com/itm/200748699775?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649#ht_500wt_1413 The seller is now trying to talk me into accepting a third generation iPod Nano instead (?). No way. Are these worth that much more in used condition? I know MIB they're a true collectable but I figured once they've been used a bit the value wears off pretty quickly. Thoughts?
