HI,
I love my HPZ's. Had a 3100PS 44 for 6 years. A workhorse. Frugal on ink and reliable. What doesn't have some issues from time to time? All fixable.
Just got the 3200PS 44. Yes the reds and performance have improved, it's almost perfection, now. I profile all media, and love it all.
BTW, HP tech support has improved tremendously, and they are "trying harder" all the time.
BTW, I did the belt job. You need space and patience, but it is do-able.
I hope these comments help. I say go for it.
So long for now, TOM
