Recently had a sour eBay experience buying a 28S, was sold as working but one of the rows was completely dead. Did get a full refund but I'm a bit disappointed with the lack of access to the internals of the calculator.

I'd really like to have one, but I worry that in the long run it will suffer the same fate and become more of a display item than the working piece of history I'd prefer it to be.

So I'm just curious if any of the other models are a bit easier to maintain? I have no issue spending the money on a nice one but I'm concerned of its longevity.

IMO your best bet is the DM-42S, not exactly HP from the golden era, but with the exception of the keyboard, everything else is excellent and far superior to HP's.
All good HP calcs are nowdays old enough and not being "serviceable" isn't make them good buy.

"IMO your best bet is the DM-42S, not exactly HP from the golden era, but with the exception of the keyboard....."
could you elaborate more on that; what is exactly the problem with the keyboard?
is it just stiffness issue? or a build-quality issue?
