Most common calculators in the forum?

[EdS2]

This poll needs more Sinclairs... here's what I've got, working, not working, and not even a calculator:

Sinclair Scientific (working)
Sinclair Scientific (eviscerated)
Sinclair Cambridge Type 2 (eviscerated)
Sinclair Cambridge Type 3

Commodore PR-100 (programmable)
Commodore SR7949 (scientific, 12 digits displaying only 5+2) (eviscerated)

Texas TI-57 Programmable (eviscerated)

HP-15C Limited Edition
HP 35s
HP 30b
(All HPs still working)

Casio fx-115s (just £2)
Casio fx-82ms (also a bargain, a modern high school choice)
Casio sl-300 (solar, very basic, square root, percent, memory)
(All Casios still working)

Sharp Scientific from the 70s with some kind of solver (Edit: EL-556D, actually from the 90s it seems)
Sharp EL-506P scientific, statistical, number bases
Sharp EL-9300 graphical, programmable, statistical
(All Sharps still working)

Also the kit emulations (hardware and porting by Chris Chung, original software by Eric Smith):
NP-25
MSP-430 - TI Datamath 2500 and Sinclair Scientific
(These are working)

Mechanical:

3 slide rules, two at 6" and one at 12"
Magic Brain
Abacus (two)

A few no-name trivial calculators:
Solar-only with memory, square root, percent (working)
Solar-powered credit card sized (working! From the 1980s)
Two with square root, percent, and memory (probably the most-used calculators, both working)
A no-name calculator watch (Edit: named Advance)

A couple of personal organisers with calculator function:
Sharp EL-6320 Memo Master Alarm
Aurodis DM320 Organiseur Personnel

And, not calculators, but well-loved, handheld, battery powered, and capable of calculation (spreadsheets, OPL programming):
Psion 3a (512kB)
Psion 3a (1MB)
Psion 3mx (2MB)
Palm IIIx

And what do I use? Usually Google and sometimes awk. Rarely a calculator.
