Singer 401and 404 both fit in either bag, with height to spare. I'm not sure about the standard Singer wooden bases yet. It will be a snug fit, if they do go in there. The 404 doesn't seem too heavy for them. The 401 might eventually prove to be too heavy.
I researched cases a bit, and to get something better you'd have to go to a $100-$200 Tutto, or to $200 & up for ABS or aluminum hard shell cases, and I am not even certain that those have sturdier handles. If one wanted to put a lot of effort into it, one one could probably find a good carryon (luggage) bag, or some kind of catalog case, or a tool case or something, that will handle the metal machines better.
I decided to keep both of these totes because the price was right. I suspect that some of the broken-handle complaints are from people who picked up and/or carried these cases by the handle. Whatever. If they break, I'll toss them and get something else. They will work well enough for carting the Brother plastic wonder and the Singer 404. I got the Bro for free as an award, and the 404 with its cabinet and stool for only $10. I don't want to spend $200+ on cases for those machines, hehe.
