I'm also on back order for a relay by couple of months too, but also cancelled an order recently for a couple of switches that I was able to get from a local vendor (albeit at a higher price). In that instance I couldn't wait as it was a long lead time and they were needed for something important at home.
ASI is still my preferred vendor though! Cant beat the prices, customer service and range of products!
