I have seen the new smaller model. I own the full sized model. I think the full size one is good for commercial, but the smaller stripped down model is good for hobby users. They are still expensive, whichever model you chose. I think the extra cost for the full version is worth the money, despite being heavier - it is also more robust.
I own the full size but I'm getting the smaller model. It's an overall upgrade to the full size model. Better heat management, works for commercial beekeepers better due to the design. Make no mistake. It is an upgrade to the original. Not sure why they are still selling the og model
