+1 on Sasha's recommendation. With this caveat:
I tried going that route with a click BP that had my friend's business information on it -- it was a freebie when I bought some stuff from her, most notably a set of cotton cards (for processing cotton fiber, prior to spinning -- they have finer and more teeth than standard wool cards). I liked it because the barrel on the pen was purple, and because I like supporting my friends' businesses when possible.
The package of refills I got from Staples was blue ink (the original filler was black, but I tend to dislike black ink, and switching over to FPs hasn't really changed that). Staples used to carry ones that were pretty good, but the last time they had gone over to ones that were under their own name and those refills were AWFUL -- they leaked before I got the blister pack open! Needless to say, they went right back to Staples for a refund....
