The Hoffman boxes do depend on a good coat of paint to protect the
surface where the door gasket seals. Mine showed surface rust is less
than 8 years with just the factory primer.
Whether a heavy duty Plastic replacement box, or the Hoffman box (both
can be installed on the tower just like the original., installing the
components can be done in a few minutes with hand tools at a savings of
nearly $900. With no limit switches, the cost of new components is
around $10 - $15 excluding the electrical box.
I could afford the factory box, ready-to-go, but even with one hand it's
an easy installation.
I'd definitely want limit switches. They are good insurance.

My LM470 uses a plastic replacement instead of the Hoffman box (PVC?) and
they don't rust.
