parts started breaking after ~3yrs of on/off use.
that's really good for 3d printed abs.

I've had pla parts outside for a around 6 years - but they just sit in the english weather and aren't really stressed much.
Abs doesn't really like being outside.

But 3 years of actual use from 3d printed abs is pretty impressive.

As far as large sized enclosed dual extruder machines go.

There are a few around - not sure how many come in belows $5000 dollars.
Don't know anything about affinia - looks like they make two printers - neither one is dual extrusion.

But they do warn you about using abs:
ARNING: This 3D Printer – when used with a styrene filament (ABS / HIPS / or PC-ABS) – can expose you and others in the same room to styrene, a chemical known to the State of California to cause cancer. www.P65Warnings.ca.gov.
First time I've seen one of those.

From a forum users point of view the raise 3d e2 has been thoroughly tested by bikeracer 2020.
Who also had a flashforge creator 3 and had problems with it.

It's good spec IDEX printer, a decent price and an impressive build volume: 13×9.4×9.4 inch | 330×240×240
It also has a hotend that runs up 300c.

Worth a look on your part.
