Chase Ink Cash Business credit --- $20,000 for my sister!!! $200 cash back after $3,000 spent in first 90 days. She was expecting a LOT less, so understandably a very happy camper today!
Another vote for CSP. I picked up the tab for dinner with my sister, and the waitress commented on the weight and heft of the card. It was the first time anyone had ever commented on a card that I presented for payment. She also wanted to know how I got it, etc.
