Which HP12 to buy?

[rprosperi]

Just to be clear, these are the ones to get, and not get:

Do get (examples just to show exact style):

17BII and 17BII+ Silver

Do NOT get the 17BII+ Gold

Note that there are actually 3 different color schemes of the 17BII, but they are all equally good, as long as there is no "+", you are safe.

Most used 12Cs do not list the country of manufacture in the description, so you usually need to examine the photos, or sometimes ask the seller to check the back of the unit.
