My order was filled and received within 2 days..they were a pleasure to work with when I called them...If something was backordered the rep that I was working with would inform me and together we found an alternative..
I can't speak on their fulfillment of backorder shipments, but they've been pretty decent on in-stock parts!!!
Oh...and you won't need to worry about it as much now anyway..you're not restricted to Serpent for Xray parts..just about every LHS seems to deal with Horizon...and Horzon is not also handling Xray...so if Serpent ticks you off...call your LHS and you'll be all set
