That’s exactly was my thought. I figured I’d have it forever, if I figured getting the newest one was the way to go. If I got the b3, when a b6 comes out I’d want to replace it. I found the last b5 on eBay, Unfortunately it cost me 50 dollars more than midway. But nobody is gonna have this in stock for a very long time. So I went for it.I don’t know what the price difference is, but the press should last the rest of your life. I bought the B5, and have absolutely loved it. The primer collection works like a charm.... maybe it didn’t on the B3?
