just wondering why it the Russians have The DHD that was found with the first stargate on Earth. Could not they get one from somewhere else like a world that going to bury their gate or some place that doesnt need it. Several worlds would have been great options for this (since the gate might be burried forever, ect). Even if it for some reason isnt quite the same better to Have a DHD then not at all. Maybe there is a problem with a dialer going thru the gate?
