I also picked up one of the 432s when it was discontinued. I had an SP101 I picked up from a friend- fun but heavy, considering the teeny little cartridge. The 432 was lighter and cheap. Don't remember exactly, but it was less than $350 with shipping and transfer fee.
I like 38s, but I'm more accurate with the 32 and get faster followup shots. And it's fun to shoot, rather than brutal, so I practice more.
It's what I carry when I'm not carrying. If I'm going into the wrong side of town, I carry a semi auto. But my everyday hanging out at the house, or at the office gun is the 32.
What I'd like in a 32 5 shot revolver would be something more like a H&R Young America (not a break top). I don't have one anymore, but I'm pretty sure it was smaller than an I frame. I'm thinking with 2014 metallurgy instead of 1905 metallurgy, you could chamber it in roughly a 32 acp size cartridge with a full rim and load it to 35K PSI like a 9mm or 40.
I wouldn't expect S&W to do it, though. Maybe a company like NAA.
Something scaled up to 32 from a NAA Mini would be neat, too.
