Both of the popular new Juniper cards - US Airways and Midwest Airlines - follow the typical 1+2% method.

I use SPG Amex as my primary and my credit union's debit card as my backup while abroad.

I figure I'm still coming out a smidge ahead buying Starpoints for 2 cents, and my credit union debit card doesn't seem to pass through any charges that I can tell (vs. that day's interbank rates). I also get three free ATM hits per month worldwide with the debit card, which is plenty unless I'm hitting a lot of different countries.
