HOWEVER -- i love the multi-layered stencil pieces that I've seen put out by SHAG, Bosler, BryanC... and hopefully one of these days I will take the time to try one out on my own. :) Those pieces, in my opinion, are awesome and worth more money than most of those guys charge because of all the time and effort that goes into them.

Here's another point of view about VALUE:
If you're all about going to a show and selling a bunch of 11x14's quickly because of their extreme popularity, then I think stenciling could really pay off and then if that's the kind of 'value' that you're seeking then I would say it will be worth it. But it wouldn't be the multi-layered stuff though... just basic silhouettes on a cool background... Do 'trendy' stuff like Marley, MLK, Jesus, the Cross, maryjane leaf, etc... like basic 1-shot deals where you put more effort into the background than you do the actual stencil... In that case it's all about having the right stencils that everyone can relate to. I've seen videos of lots of guys selling very basic silhouette paintings every few minutes because they're broad enough that people can relate to them, and they're cheap enough to get the impulse buy from someone just passing by. But to me it seems like that becomes almost "cookie-cutter"ish... not much thought because you want/need to sell. I saw a video of a guy that offered a HUGE range of quick stencil pieces and as soon as he sold 1 he would pull out the stencil for it, spray down a new one and put it right back out in the same spot.

But like I said - that's just another point of view regarding whether or not it would be worth it.
