    I have been using HP calculators for 60 years and would use nothing but RPN input - recommend that school children are introduced to RPN at their first calculator rather than wait till high school or later.

      There used to be an Hp 18c, a business calculator. That is the only Hp 18 calculator that I KNOW OF. You could also be looking for an Hp 38G, which is quite a bit different. Neither are similar, so you will need to be specific as to which you actually are looking for.
      An Hp18c is the forerunner to the Hp 19b which is also discontinued. It is a business calculator, however an Hp17Bii is still available and very similar aside from the wallet type layout of the Hp 18c.
      The Hp38G is a graphing calculator and also discontinued. It does have a modern, better replacement of an Hp39Gs.

      Perhaps you meant the Hp 48Gplus. It is no longer available new. However, it can be found used, if you expand your search to the plain 48G, you will certainly find one. The difference is less memory. There is a GX version that can take expansion cards, but is even more expensive than the 48Gplus. The new replacement is the HP 50G and it is a nice upgrade. Nearly as good of keyboard, although the enter key is shrunk and moved to lower right corner.
