I only have two Ms, a 300 and a 450. FWIW the only multi-coated LF lenses I have.
The 300M rides aboard a Gowland 8x10 aerial camera where movements aren't possible, while the 450M does the job on an elderly, little used 12x20 Folmer & Schwing.
As to the OP's concern I'd have to say the 450M, in good condition, would certainly be an excellent choice as would be the Fuji or an Artar
--- although with an Artar you'll likely have an older Ilex shutter, which I'm personally quite happy with.
As a poor bottom feeding hobbyist, I tend to jump at what's available in good condition at prices I can afford.
That 450M sounds to be a worthy addition if it is as described by the seller.
Let us know what you eventually choose and how it's working out.
