I received my Sci-Fire Chest Display today in the mail, from Clark James. I have never owned or seen any of the other member's displays (like Shackman's, which I know is very highly regarded) so I cannot compare it to anyone else's work. I must say I am impressed with the work of Mr. James. The piece seems constructed well, and includes a plastic housing to protect it. The unit was shipped very quickly, and was packaged well, arriving in an anti-static foil bag, and it includes 3 pages of instructions and information, including templates to cut the slots in the armor. I also like that you can easily switch between the DP display and the ESB display. (Not sure if any of the other displays out there are capable of this.) The one small modification I plan to make before permanently installing it in my armor, is to add a small piece of green welding visor material (left over from cutting out my visor) between the display and the back of the armor. The LEDs are BRIGHT. Adding this piece, in my opinion, dims the lights just enough to where they are still very visible and vibrant, but not hard to look at. (Also, the layer of plastic will protect the inside components of the display from the elements.)
With this being such a new product, I was naturally somewhat skeptical when I ordered the display, but after having received it, I am happy to vouch for Mr. James' work. Overall, it's a solid product.
