Considering 35s acquisition

The keyboard is indeed a nightmare and precludes the use of these calculators as a practical tool. But they are a labor of love (as so many other projects) and I gladly support such initiatives. The Swiss calcs are so nifty that you cannot withstand acquiring one (or the whole set).
While I admire the hardware aspects of the 15C LE (save for its battery usage), I wonder whether even a PCB replacement would be necessary. Perhaps a firmware rewrite would be all it takes to activate the extra memory capabilities of the Swiss calcs. Perhaps the 15C LE PCB already has the extra memory capacity required. But I suspect we will never see such a firmware update from HP.
Compare the attitude towards the PSE bug with the attitude of Dave Packard when the HP-35 bug was discovered (link). And HP would not even have to refund or repair them. They would only have to issue a firmware update. Sigh.
