You can get wired remotes that attach to the 10 pin connector for less than $10 each.
Actually it's 40% of the resolution, assuming you can extract everything the D3200 has to offer. Since the D3200 does not have Mirror lock up and the D300 does, often the resolution difference between the two will be far less or could even favor the D300s.
I happen to have a D300 and I love it - got it secondhand a couple of years ago - but most of my birding has actually been done with a D70 which in some respects I prefer for birding because of the proper high speed x-sync.
To force me to learn how to use the camera correctly 
The D300s will give you musch more control than you can achieve with the D3200. The main drawback is that the D3200 has a new sensor that works better in low light and high ISO ...
Yes, but it's still nowhere near as user friendly as the build-in IR receiver on cheaper bodies. And you need to find an off-brand one to get to $10.
Can't you extract 24 MP from it?
Don't forget that with a D300s there is nowhere to hide ... there is no 'auto' or 'scene' options. It's PASM only. On the positive side though, you will learn how to use these better as you cannot just be 'idle' and flip to auto-mode. This is actually one of the reasons I moved from D90 to D300s
Whorty, that's an interesting reason for acquiring a D300: being forced to do photography properly!This is actually one of the reasons I moved from D90 to D300s
LOL ... it was just too easy to switch to an auto or scene mode and I was just being idleWhorty, that's an interesting reason for acquiring a D300: being forced to do photography properly!This is actually one of the reasons I moved from D90 to D300s
I actually loathed those scene mode icons on my D70 and of course never used them. To me they cheapened the camera: a bit like having a Mickey Mouse icon on the camera!
With the D300s I have no choice but to think about the light and exposure etc. I'm not sure it's made my photography any better, but at least now I understand a bit more about how cameras work - ha ha

. Nothing is more user friendly than a simple on/off button, and my experience with off-brands has been very good.
You can often get more resolution from a 24 MP camera than from a 12 MP camera. Nonetheless, under absolutely ideal conditions you never get more than 40% more linear resolution (just do the math comparing the longest axis on the 24 MP sensor to the longest axis on the 12 MP sensor).
I use mine all the time for landscape and macro photography. I can see the difference between using MLU and not in many situations, so it's pretty much used whenever I am using a tripod. Now if I can see the difference on a 12 MP photo, then it stands to reason that not using MLU on a 24 MP photo isn't going to get you any more and often will get you less than you could get using MLU on the 12 MP photo.
