We have 9430DC in stock now, 6105's should start to show up again in June, this pump in particular has been a victim of electronics component shortages, we haven;t had any since November but this is partially resolved and we should start to get them again soon.
I am unsure on the 6105s, I dont have any on the way, the last info I got was they would start shipping them in June, but if that is the end of June, I won't have them here until early July.
I did get word they are able to produce them again, but given shipping right now, I would say that January/February is the most likely, they do have all the parts needed to make them now.
