For those of you who like older mechanical machines like the featherweight, consider the Kenmore 158 1030 (also 1040 and 1050), aka as the rose Kenmores. I have a featherweight but the 3/4 Kenmore is my absolute favorite portable machine. My Rosie is awesome and cost me less than half what I paid for the FW. And she still had the hang tag on her handle! Brand new! Here's a website that talks about them:

This series has a tool storage bin that actually tilts out to provide a larger flat sewing space ahead of the needle. The only problem I have with Rosie is that my sister keeps borrowing her for longer and longer periods before I get her back! LOL!
Like all mechanicals, she's a tiny bit heavy but she stays put pretty well and I have no trouble carrying her as I approach 70. When she gets too heavy, i'll invest in an old lady cart for us.
