When looking for threads you may sometimes see people using the names NovaTac and HDS or HDS-EDC as if they were the same company. They are not the same company, but you may be interested in the HDS as well because the two lights are related.
A member of CPF made some very high quality, and very expensive lights. This company was and is called HDS. They do not have any products for sale now, but they say they are designing some high end lights that will be released later.
NovaTac is a new company, but I think most reports about the quality have been very good. I don't have a NovaTac so I can't say one way or the other. I do have an HDS that I like very much.
