Well, the USPS representatives & website still
say the package is in Florida, but I was told by
the person I sent the cel to that it arrived
today (unharmed!).  ^.^

Furthermore, my lovely art is still sitting at
the dealer's gallery.  The invoices were 
accidentally switched, and this one was mailed,
but mine was still being packed.  So crisis is
now averted.  =)

Thank you all for your suggestions!

(I still think the post office skimps a little
more on service every day, though... and I 
will not be extremely wary of "guaranteed
tracking" methods...:P)
