Thanks for your replies in this thread.

Technically, that is true of any plastic part. Which is why I find it very interesting that people pay upwards of $350 for scratched and dented HP-42S's! I can understand the nostalgia, but paying that kind of money for an item that might break due to the sheer age of the plastics is troubling.

But in my case, I didn't buy my 28S off EBAY. It was a purchase through my university bookstore back in early 1990. I've used it regularly through the years and only recently noticed the key problem. Thankfully I have a solution. I just need to make a little more effort to press a finger against the back of the case and the key then registers. It would be nice to have it perfect, but in light of how old it is, we can't have it all.

Now if we could just figure out how to put a 50G into a more beautiful case, akin to the legacy 48 series, that would be ideal. I'd love to have a modern HP calc with powerful functions and the legacy layout. Who among us wouldn't? Funny HP doesn't recognize that segment of the market.

Best wishes.
