Like you, I regret not getting a 315NG. You could argue that it was the most useful of the bunch. That being said, I've carried my 325NG a lot. It took a while to find a holster that met my needs, but it was worth the effort.
These revolvers are very specialized guns, and they actually appeal to a rather small portion of the population. The N frames especially are difficult to carry concealed. They don't weigh much, but they take up a lot of real estate. I don't find the recoil on the 325NG to be much of an issue, mainly because of the soft factory grips. But the big magnums are another story. Last year, I put 24 rounds through a 329NG, and I knew I was making a mistake about round number four.
I think you (actually Motown, sorry 'bout that) are right about the sticker shock. I paid about $880 for mine, including tax, title, license, and my recappable tires. That was when they first came out. I think the NIB prices are higher now. It's a lot of money to spend unless you know you are actually going to use the thing.
