48SX options

[rprosperi]

I recommend you get a used 48SX from eBay, there are many available there now, including several that are well under $100 with shipping included.

Taking a stressful test is no place for a new machine, even a similar one. And if you're thoroughly used to RPL, even a good RPN machine can feel "not quite right" under pressure.

Get a new 48SX and focus your available time on the study topic and the test, relax with a comfortable tool during the test, and enjoy having a new 48SX friend around after you pass the test.

And I have to strongly disagree with Max about selecting a Prime. Though an excellent machine for which it was designed, teaching High School kids Math, it is totally unsuited for use as an Engineer's tool, especially for an RPL user. Its RPN capability is primitive, non-intuitive and awkward to use at best, and trying to wrap your mind around it in time for a looming test will be impossible. Also, it costs more than a 48SX and you likely won't use for future work, unless you intend to go back to school or explore Python.

Just another viewpoint.

And good luck!
