Oops! While waiting on something else, I just stole a glance at C.net , determined to read little and respond to nothing. But I saw "Crane" and looked at this thread, and when I saw an error of fact that no one else had corrected, I couldn't let it lie. After writing the following, I will once again fade into the background.

Perhaps that a duet that goes down to middle C on the right is worth 50% more than one that doesn't ?

Seriously -- IMHO, a Duet is worth a
lot more if it goes down to Middle C (as do all (?) Hayden Duets), rather than cutting off at the G above. I know that small Maccans and Cranes cut off at that G.
Sorry, but that's not true. Every Crane/Triumph I've seen -- either in person or for sale -- has gone down
at least to middle C in the right hand and to the C an octave lower in the left hand. Even 35-button Cranes go down to those two C's. And standard Cranes are fully chromatic all the way down, though the Crane 35 omits a couple of accidentals at the top end of the left hand and the Crane 48 omits a couple of accidentals at the top of the right hand.

In fact, I hope to live long enough to buy and play a Hayden that goes down to Fiddle G below Middle C on the RH.
I've seen a couple of 55-button Crane Ĉolas that go down to fiddle G in the right hand and down to the G an octave below that in the left hand. They are relatively rare, but I know that there are at least a few more out there. They pick up the extra low notes by cutting back the top end in both hands, so they're sort of a fourth lower than the usual, though they still keep the key-of-C notes in the center three columns.
As for Maccanns, I suppose it depends on what you consider "small". I'm pretty sure that Wheatstone's standard 57-button "duets" (they never used the Maccann name) go down to middle C in the right hand, though on the 55-button Lachenal Maccanns I've seen the lowest RH note is the G above that, as it seems to be on any Maccann with fewer than 55 buttons. (Dirge, please correct me if I'm wrong.)
