HP
4 HP15C this is THE CALCULATOR! Best form factor ever! The only calculator that was brought to life after more than 20 years
discontinued. This is for a reason, isn't it?
1 HP11C like the 15c, but less powerfull
3 HP48GX luv it. A pleasure to use. I prefer using them instead of the 50G.
3 HP48G
2 HP48G+
1 HP48SX best keyboard ever. Soft and precise.
1 HP27S a pleasure to use. A Swiss army knife. Luv it. The pioneers have great keyboard, but should have being made landscape.
2 HP17BII powerfull solve.
1 HP50G the ultimate evolution of RPL. Very mature calculator. Its only drawback is the small enter key. But doesn't have the 48 quality.
3 HP28S with 32 kb, now we can program with a 28. Simply fantastic calculator, a pleasure to use.
1 HP28C historic.
1 HP41CV luv it. No need to say anything. If you want an opinion, ask Massimo.
2 HP49G although its rubber keys, a pleasure to use. I like it
1 HP71B The King. Enough said
1 HP18C good only for its solver, but a historic calculator.
1 HP19BII very nice, with Rpn
1 HP19B good finance with some scientific features, but no RPN.
1 HP32SII really big font, my weary eyes say thanks and very powerfull. Small programmability. A pleasure to use
1 HP35S like it.
1 HP33S ugliest calculator ever. But I like to use it. Some keys sometimes missing keystrokes. Useful
1 HP12C 30th anniversary edition. What to say about it? Its longiviness says all.
1 HP33C a pleasure to use
1 HP30B never used
1 HP42S do I need something to say about it here?
1 HP97 luv it. Best led display ever. Big and crisp.

TI
1 VOYAGE 200 very powerfull and with its qwerty keyboard, it's what is a usable 89 TITANEUM. A pleasure to use and a must.
1 NSPIRE CX very complicated, confusing, really tiny fonts, but powerfull and with colours. Dispensable.
1 TI89 TITANEUM forget
1 SR40 LCD my first calculator that I purchased in 1981. No money for HP. Only made in Brazil, really rare. Keyboard disaster, it only lasted 1 and half year during high school.

CASIO
1 PRIZM with CAS (eigenmath). With its colours and super easy to use, a really pleasure. A must for calculators lovers.
1 FX-802P
1 FX-850P
1 FX-880P powerfull, very handy with its built in functions and with 32kb + 32 kb memory pack = 64 kb lots of memory to play with
1 PB-700
1 PB-770 like it
2 FX-101 from 1976.
1 FX-4500P
1 FX-3600PV small and thin, solar, small programs yet powerfull.
1 FX-7000G historic. First graphing calculator
1 FX-7000GA

Sharp
1 PC-1500
1 PC-1402
1 PC-1421

I probably have more, but I don't recall, and these are the most important.

Cheers
