If I were to buy an LED model...

And if the opportunity to snag a cheap (relatively speaking) 25 or 55 presents itself, I'll take it.

I'll second the 45. It's got a pile of improvements on the 35 (especially y^x instead of x^y) and a bunch of added functions via the shift key, but they are for sale cheap quite frequently. In the last couple of years, I've twice gotten ones from the auction site that were virtually perfect... no corrosion, no initials carved in, no used-up keys... both really good machines. One cost me $50 with shipping and the other $30 with shipping. The $30 one was exceptionally cheap, but I've seen others not too infrequently around $50. They are a great value and only cheaper than the 35 because they came second.

True, it's not programmable, but as an ad hoc number cruncher, it's exceptional and SOLID.
