WP 34S: Is it becoming a sought-after classic RPN machine?

[jebem]

Have a look to this TAS link.

I think the asking price is right.
I spent more than 70 Euros (including a small donation to the creators team) to build mine, and I had to build my own programmers cable as I have joined too late to this party to be able to get a HP original one.

I like the nice advert of the 34S feature's summary from this seller (whoever (s)he is):

There is simply no other calculator offering so much mathematical power and accuracy+precision in such an small&light pocket size.

If you are looking for this, you know what it is. Easily the most powerful non-graphing scientific calculator on the market, it has been expanded with all kinds of functions, distributions and constants for all your mathematical needs.

Used (with love and care) just for 3 months.
Reason to sell: I will miss it, but I need cash ASAP.

Clock crystal installed!

It comes with:
USB PROGRAMMING CABLE for firmware upgrades and communication.
Original HP30B slip-in case.
Spare keyboard stickers included! though my guess is you will never need them, taking into account the dedication and quality of the DIY job :0)

Flashed V3.3T3844 firmware.

Some of the features:
+ Selectable 4-level or 8-level RPN Stack Size.
+ Hundreds of customizable registers.
+ Euler’s Beta and Riemann’s Zeta functions, Bernoulli and Fibonacci
numbers, Lambert’s W, the error function, and the Chebyshev, Hermite,
Laguerre, and Legendre orthogonal polynomials (no more need to carry
heavy printed tables).
+ Many statistical distributions and their inverses: Poisson, Binomial,
Geometric, Cauchy-Lorentz, Exponential, Logistic, Weibull, Lognormal,
and Gaussian.
+ Programmable sums and products, first and second derivatives, solving
quadratic equations for real and complex roots.
+ Testing for primality.
+ Integer computing in fifteen bases from binary to hexadecimal.
+ Financial operations such as mean rate of return and margin
calculations.
+ 88 conversions, mainly from old Imperial to universal SI units and
vice versa.
+ 50 fundamental physical constants as accurate as used today by
national standards institutes such as NIST or PTB, plus a selection of
important constants from mathematics, astronomy, and surveying.
+ Battery-fail-safe on-board backup memory.
+ Greek and extended Latin letters covering the languages of almost half
of the world’s population (upper and lower case in two font sizes), plus
mathematical symbols.
