I have the 33s (http://www.shopping.hp.com/product/calculator/HP/1/storefronts/F2216A%2523= A BA;HHOJSID=3Dhk2NMZ2p2JYsTWYH3XBBZpmp2Tnl2xS0N8lPv0llJ29L7YNS17fK!423885936= ), which is a decent enough calculator and does RPN. It can also do algebraic= , but I only use it in RPN mode. It's main shortcoming is that I'm used to a 11C and the horizontal format. It also doesn't feel as solid as the 11C. = I don't expect it to be around 28 years later like my 11C is. The 33s is onl= y $40 direct from HP. One nice thing about it is that it uses the widely available CR2032 coin cells. HP also makes the 35s for a few dollars more. Then there is the "12C Platinum", which looks to be a remake of the original 12C. Apparently financial people appreciate RPN too. Who'd have thought!? And there must be more of them than those that want the 11C or 16C. There don't appear to be current versions of those at all. ******************************************************************** Embed Inc, Littleton Massachusetts, http://www.embedinc.com/products (978) 742-9014.
