It is usually cheaper to get a better quality print out from a real print lab than printing at home.
However, there are times when you want to get a print done quickly.
It is common for printer manufacturers to claim that third party inks are the cause for problems.
Generally I have found that on the two occasions I have used third party inks, they have caused problems. Most recently, somehow, the magenta from one cartridge is leaking into the yellow, and ruined a genuine cartridge.
If you move to third party, make sure that you keep a set of real ones to put in if you have to send the printer off.
