Why it's buy-it-for-life
Owners describe the 251-3 as a solid, heavy-duty machine that can rip through straight-line seams on thick or heavy-duty fabric, with one owner (a machinist who has several) calling it 'awesome' once you learn to time the needle to the bobbin and tension the thread. It's not maintenance-free and behaves very differently from a domestic machine: one commenter gave up on theirs, and others note the foot pedal and knee-lift take time to get used to, so it best suits owners who are handy or have access to someone who can service it.
What owners say
Commenters generally rate the 251-3 as a solid, heavy-duty industrial well suited to straight-line seams on thick fabric or leather, though several caution it is not maintenance-free and operates very differently from a domestic machine. One owner and machinist calls the machines 'awesome' once you're familiar with timing the needle/bobbin and thread tension via the manual, while another says they gave up on the same machine after finding it too different from a domestic to manage. Others note the foot pedal and knee-lift can be tedious to get used to, and that it's better suited to repetitive straight seams than intricate or varied stitch work.

I have several of these, but I am also a machinist. They aren't hard to work on, but you'll have to familiarize yourself; just find the manual and read it.
It is heavy duty, but it's very different from operating a domestic. I eventually gave up on it.
I always had trouble being coordinated enough for the knee pedal to raise the foot.
If you need to rip through a shit ton of straight line seams, they are great.
They are solid machines, but if you aren't used to a foot pedal, just be aware it can get tedious.
