The Priceline Visa card is tempting, as the Flyertalk thread has good reports of it being basically 2% everywhere with no annual fee. There are also Name your Own Price bonuses.

You might consider another Barclay's card, the Choice Privileges Visa Signature for daily use. The signup bonus isn't great, but I just looked and it gives 2 Choice points per dollar with no annual fee. Choice has plenty of hotels at 6000 and 8000 points. I actually transferred Amex to Choice this spring to book in Rome, Italy, at 8000 points per night. That would be $3000 to $4000 spending per night.

I think 1 SPG Starpoint is worth more than 2%, but I like midscale hotels and airline miles.
