The obvious choice is the HP12C Platinum, which can operate in algebraic or RPN modes. The default is RPN. They can be found new. If "not new" really isn't a deal breaker then you can also find plenty of HP12C machines in asgoodasnew condition on TAS among other places. I have 2 or 3 of them in pristine condition. Another option you might like to consider is a fullblown scientific calculator that also has a finance application built in. I'm thinking of the HP Prime here. It'll do some RPN, although it does seem to be a bit of an afterthought and you can only program the Prime in HPPPL (a Pascallike language, but damn fast because compiled rather than interpreted) but it is still available new in some places. The finance application was added, I believe, with the latest firmware update released last month. I can't speak to the other HP machines you mentioned because I have neither one in my collection. I do have examples of the 12C, 12C Platinum and Prime.
