The 28/128's are nice little machines, especially if you're going to piece with it using the handcrank. (You don't notice how fast the bobbin runs out!
)
And the beautiful detailing on the plates is so charming. I have had three 128's, but gave away both of the hand crank versions, one a Roccocco and one a Victorian. I still have one in a treadle with Victorian decals. If I ever found one with nice La Vincendora decals, I would buy it in a heartbeat.
One nice thing about the 99 is that there's one around every corner. There were so many of them made and eventually, one will come along at a price that is right for you. It took four years to find "my" Featherweight, but be patient and you'll get your 99, too.
