We've used an older Elite XL 808 in my office for roughly 5 years now – 133,338 pages printed – and it has proven to be fairly reliable. It has been services a couple of times (bad fuser) and of course it wasn't cheap to repair but has been fine since.
Toner is expensive however, catridges are $199/ea. from GCC. But, as a 11x17 full bleed printer, it is excellent and would recommend one highly.
