We bought 5 at WalMart today (and now have 2 of each color combination ... do you think that the reason that FIRST picked the color combos for Lunacy is that that's all the manufacturer makes?

). Of the 5, three were broken. We got the good ones for $10 apiece, and the manager gave us a $1 "discount" for the broken ones (thanks, buddy). Fortunately, two of the broken ones appear to be fixable (the break is at the joint), but the other is really broken.
We are speculating that we can carefully swap out a fixed segment from a broken one, thus making a good one out of two broken ones. Grrrh.
