Not sure what you're getting at.

If you're talking about a 'deal' on the lightbar, I don't see where you get that from. It's not something the guy is gearing-up to mass-produce, or even to sell as far as I know. I mentioned it in passing that some others may want one, and he said it would cost at least $175 or so, but he would have to figure it out if people were really interested.
I know he worked about 6 hours on this piece, and that was with one part already being done off the shelf for another project.
If several people want them, he would have to take mine off and make a jig for it.
If I get a feel for how many people are seriously interested, I'll ask him and see what he thinks.
I don't think that $175 is unreasonable though, and no, I'm not making anything off of it. He's a neighbor and friend of mine.
