How rare are 273 Commando factory pistons .030 over ?

Just bought new Egge 0.030 over 273 Commando pistons for my build. I think there were a couple other places with them available, but Egge had them in stock and they get so much publicity here I went with them.

EDIT TO ADD - "Just bought" means my builder had talked to them and got my approval, then in the late spring when he called to order Egge said that they did not have enough to give a full set. A couple days later they called back and said they found an 8th piston and could fill the order, which they did in late April with delivery to my builder. He billed me end of July, so I said 'just'... but it was relative. :thumbsup: If they had not found that last piston, we'd have been looking at fall delivery at the earliest as they had some issue with a master casting and had to have it replaced, or something like that.
