Wow that is a high ship price, we've been ordering from Atlas Screen supply, so far good price and shipping ain't bad, don't know what emulsion you all use but they may have it, check them out.
Oh what's wrong with Ulano Orange? we use it here all the time, works great on our LED unit, you can also try Atlas supply emulsion Blue works, that's our #2 emulsion, price is great and it works well on our LED and very easy to reclaim.
