For Roland sc-540, Jetbest or Sam-ink?

[xmb271]

I'm new to here and try to find a good after market ink for our Roland sc-540. Searched for all inks and found jetbest and sam-ink are all good. but someone told me sam-ink is good for HP and Jetbest is good for Roland. I have no idea at this moment. Does anyone use those 2 inks and give me some suggestion?
Thanks again for your help!

We have a sc-545ex and jetbest works like a charm every time! Cheap too.
