I've heard nothing but good things about Dan's cues, and the one's I've seen are great looking too. The prices also seem reasonable. I met him at the BCA Nationals last month and he seems like a good guy to do business with.
I think some of the reason you haven't seen a lot of his stuff up for sale is timing. His work, while very good, is not considered in the top tier of collectibles (yet, anyway), and therefore prices have been hit harder by the down economy. And it also is probably just random. The first few months I came on this board there were several for sale. That's how I got wind of his work, was by seeing some of his cues offered here. Check back in time in the for sale forum and PM some of those guys if the cues aren't posted as sold. They may still be on the market if you offer the right price.
