Ink for HP C7280

[Atom]

I have been using bulk ink for years to refill my Canon ink jet (black only), but now I have acquired an HP C7280 and I am wondering which is the best way to go:

1. OEM cartridges
2. Non-OEM cartridges
3. Bulk ink

I'm impressed with the quality of the photo prints so I may be doing more of this than I had originally thought and since it works so well, I don't want to screw it up.

OEM cartridges cannot be reset, so you must install refillable Non-OEM cartridges with (auto)resettable chips or use a CISS-system. Search for refillable HP 363 cartridges or CISS system, but take care to use high quality refill ink (like: precisioncolors.com).
