Last I heard you could still get the bonus for switching from a Visa to a MC of the CSP, might have changed, haven't looked lately. You need to close the Visa though.
The Chase UA MP is a good one if you can get the 50k.
SWA Premiere is also at 50k and gives you enough RR points to cover the annual fee every year.
Also look at the Citi AA 50k, and US Air 30-40k (will be AA miles once merger is approved), and maybe the SPG 35k and the Amex PRG for 50k.
