Forum search functions usually suck but this one's is pretty good. You can search this thread only for posts by a user with a keyword.Forgive me if this was already answered as I am only about 39 pages in but gotta ask before it slips my mind. Form any info on the 80 eldm or eldx as compared to the 77 TMK? The eldx has promise of being a 77 TMK substitute that you can actually get your hands on.
