Old HP models are expensive because they actually still see regular use . but you can find some of them on ebay for $ 100 if you ' re patient . Keep an eye out for some more wellworn examples of the 15 c and 41 . If you ' re willing to step down in terms of capabilities , have a look at the HP 32 s . Alternatively , check out Swiss Micros for some modern reproductions of classic calculators . <| sep |> HE ' S 32 ? This has gotten so much worse and I am close to howling laughing at how inept this man is . This is the funniest shit I ' ve read all day . I cannot believe how incompetent some people are . My 19 year old boyfriend makes his whole family dinner nearly ever day with more coherence than this entire post . The day he serves any of us just a hunk of meat is the day I ' ll tell him to sit down , put his feet up and have a break and I ' ll take on the rest . Fully cannot believe this post . Like , gleeful someone out there is that oblivious to life .
