I just bought a D3200, and wasn't aware there was really that many differences. I assumed it had IR. The wired remote should work great if the point of the remote is for camera steadiness. Under $5 shipped, can't go wrong. I have a feeling that this was an issue for many with the D3100, because they added a ton of options on the D3200 for remote shutter release (Wired, IR, and WiFi using Android/Apple phone or tablets).
