Yes I did, and I found about a dozen relevant reviews or write-ups
giving me enough info to put it on my short list when I went shopping
for a new printer.
I've seen the actual output from the iP3000 in side by side comparisons.
It's very good...but that's the only thing that impressed me about the
printer. It's built very flimsy and doesn't have the solid feel that the
previous i850/950/860/960 series had - it feels like it would snap in
half at the first multi-page duplex job.
And after experiencing and hearing of far too many printhead failures
from the Canon i-series (iP series uses identical heads), I removed
Canon from my short list.
Actually I considered Canon, Epson, HP, and Lexmark. The Epsons were
avoided due to clogging issues (I print rarely and have a laser for
regular document use). Lexmark wasn't a contender due to ink costs.
Canon now has a history of printhead failure, and previous models have a
history of failures as well. Needless to say I'm disappointed in Canon.
So I bought an HP 6540 and am quite happy with the printer. It prints as
good or better than the others, costs about the same, has similar ink
costs, it's very quick, built like a tank, and has printheads in the
cartridges.
And here's something I never considered before - the automatic
alignment. It's a treat to pop in a new cartridge and have the PRINTER
do all the alignment work instead of me. It's not a big thing, but it's
a nice convenience, as is the auto paper type sensor.
Of course, YMMV.
