Kicked the week off with the GW-M5600. Outside snap due to questionable camera on phone shows the excellent British summer - 12 degrees and raining in June, awesome!
That looks like a badass calculator. And a lecture, enjoy Somewhere have a similarly fiendish Casio scientific calculator which I one knew how to use...
Anyhow decided to go with the DW-6500 Skyforce today
Best stick with what you need I guess, seem to recall we were recommended (had to buy) a Casio. Gives me a headache just thinking about all those graphs and equations now
