7XX0 series printers

Based upon folks experiences how would they rank the 7880, 7900, and 7890 in terms of performance, reliability, and serviceability for use as a piezography printer (positives and negatives).

I know that the 7880 is / has been a real work-horse (but with a very sensitive damper / pressure system); the 7900 seemed to have all sorts of problems; and the 7890??

The 7890 was the last large format printer before the SureColor series was introduced (with their associated carts / chips issues).

Thank you!
