For what it will cost just in flat rate shipping back and forth to somebody you can buy a lee push through sizer and it works on your press so no additional equipment or space needed.

As mentioned, LLA works fine in many applications, and if the bullet is the right size as cast you don't even have to run them through the sizer.

I've gone to 45-45-10 as it's not as goopy as LLA and doesn't seem to gum up my seating dies.
