If you are getting estimates from Eurooptics I would take that with a grain of salt. I previously ordered a ph2 that was on backorder because they said it would be in stock in 4-6 weeks. At 6 weeks I called to get a update. They said they were shipped and on the way to them so it would be any day. A week later I called again and was told they would look into it. I got a email saying a couple more weeks before they could get them, I was confused by this as apparently they were not being shipped. 1 month later I called and just had them cancel my order.
Long story short. I would like a ph3 and am being optimistic but not getting my hopes up.
