Where do you folks buy your ink to upgrade the poor quality rollerballs that come with the basic kits? I have only ever purchased one type of upgrade and am looking to expand and possibly do it for less money. I have always purchased the "Hauser Gigant 012" from Berea to upgrade the RT euro and Sierra kits. Any ideas on slimline style upgrades? What do you install in your Sierra pens( Or any that are parker style for that matter)?
