Just be careful with the warranty of all these Solo's for $170 etc. I contacted Arizer regarding many of these eBay cheapies and they said that they were not authorized and therefore wouldn't honour warranty. It may be wiser to spend a bit more and go with an authorized retailer that doesn't advertise below the min. accepted price of $229 cdn.
The newest Solo's have an M1D1010101, the patents pending writing on the bottom is now recessed, not elevated and says 2011, not 2010 as before. Functionality is identical although I think there may be a slight change to the programming, just by observing the behaviour of the led's. The internals are identical from what I can see.
The black is now quite glossy, in comparison to the matte (although it seems like they have been using both).
