I had a multicam that ran for 35 years, the last 10 of those were after an in house retrofit. Solid machine, but it was several generations old, and too heavy to drive fast with the stepper motor setup it was built with. We replaced it with a shop sabre IS612, and I've never looked back. There have been a couple of issues with my machine, but everything was simple to resolve over the phone. Basically all of the parts are user replaceable, which is nice, and the support folks are knowledgeable, though some more than others.
Like johnnysigns says, it really depends on what you're aiming to do with the machine. Mine also has vision registration, but the workflow on vision jobs is trash compared to something like a zund, but I bought mine to cut aluminum primarily, so it does what I want well, but would not be great for a graphic finishing business.
Good brands:
multicam
shopsabre
axyz
laguna
zund
colex
There are more, these are all pretty much top tier (shopsabre is probably the smallest outfit of those listed, but they had the best pricing when I was shopping)
