Looks like you can buy non-China ones all day for $45.

To identify country of make from S/N:

Numbers are in the format YYWWC##### where
YY
Is the number of years since 1960.
WW
Is the week (roughly) in which the unit was made. YYWW is not always exact and sometimes may have gone weeks or months without changing.
C
Is the country code: A = America (USA), B = Brazil, G = Germany, J = Japan, S = Singapore, M = Malaysia or Indonesia.
#####
The serial number within the specified week and year. (This is not included in the Earliest Serial Numbers section because all are assumed to start at 0 or 1.)

The correspondence of serial numbers to dates is only approximate. In some cases, they may be better indicators of the date of manufacture of the case or label rather than the entire calculator. With some desktop models, it appears that the date code was changed only when there were manufacturing changes. On the other hand, different versions of the HP-35 can be found with the same date code.

Since 1996, some serial numbers have been in the form CCYWW##### where
CC
Is the country code: US = USA, SG = Singapore, ID = Indonesia.
Y
Is the last digit of the year in which the calculator was made. (i.e. a calculator made in 1998 would be marked 8.)
WW
Is the week (give or take) in which the unit was made. These are not always exact.
#####
The serial number within the specified week and year.
