I just finished mine!
See post My Sableco upper! Heading out to sight it in tomorrow. Yes, you can save, I purchased a set of reloading dies, powder, brass, & bullets for my Dillon 550. I like you was going nuts trying to decide. Man am I happy with my purchase from Donnie @ Sableco. Call him and chat with him - great guy w/great quality products. Mine fits together like it was a matched upper and lower.
email me if you have questions!
