Charles Schwab Invest First Visa Signature.

2% Cash Back into a CS brokerage account which you never have to use.

No Fee.

$3000x2.0% = $60/month cash

I think that is worth more than any hotel/miles reward. It's just a little annoying cause you have to transfer the money from the brokerage to your checking. No bid deal though, its free.

EDIT: Just noticed someone already mentioned it.
