Hrm. I really thought I had a lot of that stuff still bookmarked. Apparently I don't x.x.
Here is one that sort of helped me start to move away from the every day power sword you see around all the time. It started making me think of alternative ways to get a nice powerful effect on a rather dull part of the models.
Here is the pic that inspired me to paint my power weapons the way I do now. And
here is a photo of my veteran in case you might have not seen it for a bit ^_-.
Lightning, if you use it sparingly, really doesn't look bad. It's when people use it too much and it takes over the model as well as distract you from the detail that it starts to look garish and tacky. For a lightning tutorial
I redirect you to B&C.
Btw, sorry I hadn't gotten back to you earlier with some of this stuff. I was working all day yesterday ^_-, lives to save and such, you know the deal!
