Best Business Cards?

I was wondering you all had any recommendations on business credit cards?

I have a couple that I am happy with (good features, competitive rates, NOT reported on personal credit, etc.) This last feature is important to me - I know the card will be issued partially based on my own credit worthiness, but I’m looking for cards that don’t report to my personal credit report (unless I’m delinquent). My two current cards (Chase, AmEx) do NOT show up on my personal credit.

I’m especially interested in cards that occasionally offer those balance txfr/cash advance promo offers. (I’ve been successful handling some of my smaller financing needs this way.)

Thanks for any help.
