I have just bought one after searching today, it fits the bill - MLC and 64GB were my requirements.
It should match the Transcend High Endurance card I bought over a year ago, which has been faultless.
It's such a shame about the flash memory cartel, although prices are coming down a little now:
There was no way I was buying one at £60! Costs more than the camera (INMSDX64G10-DSCAM 64 GB is £23.99 atm)
