Mermaid the one and only downside(but it's also a plus) to these machines is that they're so heavy. It's a plus because you know they're so well made that they're going to outlast you with just a little care. Yes the light gets hot. I guess that's a minus point too but did you know that LED lights are now available for most sewing machines? They give brighter light and don't get hot.
I prefer to have them in a cabinet and use a knee lever so I have a couple of cabinets that I switch out machines into when I want to use them. My favorite machine is whichever one I'm using at the time and with 70+ machines, over 30 of them being brothers, I have lots to choose from.
