I own an ELC G-1 as well two original ones from the later periods. If you want a spanking new early contract G-1, ELC is probably the best available. The goat skin is very very durable and soft, and you do not get the 'broken-in' feel even if you have worn it for a few years because it still looks brand new (except for the single layered knits.....).
There are other options of course, there are the Made in USA ones from CockpitUSA and US Authentic, which are still excellent, but that they may not be very very authentic if that is your priority. In case if you want the top end stuffs, the trio from Japan, Rainbow Country, Toy McCoy's and Real McCoy's also make G-1s, which are based on the same contract that ELC offers, but I am not sure whether they are really better apart from the aura of Japanese craftsmanships. I am not sure if we have any fellow members here who have actually tried them out.
