Doesn't matter about the power supplies too much in my experience. Most will hold their voltage high enough to keep the 'mites happy if they have enough current rating.
I wish I could say the same for A-B USB leads though. Many of them are made with partially-conductive cheese instead of wire and are simply useless for supplying current. That's fine when they are connecting from a computer to a printer - there'll rarely be more than a few mA on any wire and often virtually no current on +5v. No good for 500mA though. The voltage at the 'mite will easily fall by over a volt. The supply is still putting out 5v but the lead loses the rest.
And just to stay on topic.... :)
I have a really cheap Acer SK-9621 which, while it will win no prizes for typing experience, works well on the CMM2. :)
