So, virtually the same dimensions for a DM42 or DM32 and the original 32sII. Which is great!

Then, there's the issue of cost.

You haven't said where you're located, so I'll just give price estimates in USD and you can convert if needed.

A used 32sII in good condition is likely your least expensive option: it will run you roughly $50-150 on eBay. Average $95.50, s=27.25 for a sample set of 12. (New-in-box is ridiculous at $450.)

A brand new HP-15c CE will cost you about $130 plus the cost of shipping, depending on where you buy it. (I recommend https://thecalculatorstore.com, as it is owned by a fellow member and he provides excellent customer service.)

A DM15L will cost you nearly the same, so it's a matter of whether you prefer the SwissMicros metal hull (titanium?) or the authentic (and very clicky!) HP buttons.

Prices for used HP-15c (originals) are all over the map. A quick search of eBay showed me prices between $80 and $300, depending on condition and accessories (and greed). A quick sampling of the 12 cheapest (functioning) ones gives an average of $152 with s=39.95.

A new DM42 will cost you $253 plus shipping.

And a DM32 (new hardware, new from-scratch development) is the most expensive of the lot, at $275.



[I have a 15c/CE, 32sII, 15c, 11c, 35s, and 48g, so if I were buying something and didn't care about price, I'd get a DM42 so I could try flashing it with different personalities and pick my favorite... which I'm guessing might turn out to be the C47.]
