I have YET another question....Does the lid on the 115 stay up for you to load the chamber? I would hope so. I was just trying to see what the benefit to the automatic lid opening and closing on the 120 would be. I just found free shipping and $699 USD on the 115!
If the lid is a PITA, I'll go with the 120.
I did speak with a distributer who says the lid cracking issue on the 112 has been resolved in case you know of others looking at that model. I don't like the 24 inch depth and the hinged arms that require 2 hands on he unit to operate correctly. I want the the 115/120 because it looks to be sturdier and I like the unobstructed transparent lid better.
Do you use the special zip lock bags, and if so, do you like them?
