Is there a recommended microSD breakout board for testing SDIO?

[Anonymaton]

I was sitting down to start getting to grips with SDIO and FATFS when I realized that the only microSD breakout I have literally lacks the pins for it (missing an eighth pin for 4-bit data). I was already considering getting another NUCLEO board, but so far I can't find one that has a built-in microSD slot. 

Does anyone have any recommendations?

Right pull-up resistor, and no level shifting chips. Directly wireable to STM32 at 3.3V

There are a couple of vendors of this type of adapter.

You, my friend, are a saint. Sorry I didn't respond earlier.
