Is there any region free external dvd drives?

Hi!, i am new to here, this is my first thread!

I am using a last generation mac mini with combo drive, and a netbook. I wanted to buy an external dvd burner so that both of them can share it. However, I also want to play dvds with different region codes. I found that there are DVD players which are regional free, is there also regional free dvd drives? or should i just buy DVD player instead?

Thank you for any advice!
