Good choice of machines. My wife & I have five Singer 401A machines (1 at home that stays set up full-time and used regularly, 2 that we alternate for daily use at our shop, & 2 un-serviced “spares” that I have stashed for “just in case”), our daughter had 2 until she gave one to a friend, and our daughter-in-law has one. The DIL’s is the only portable.
As you can tell, we think they’re pretty good machines. I have a Singer 403A portable too, but I haven’t ever serviced it up and used it.
