What external cd drive?

Hardware & Accessories

I have just ordered the latest Mac book air from Apple here in the UK and before it comes I wanted to find out what external cd drives will work with the 2013 Mac book air as the Apple super drive is far too expensive at £60 due to the fact I would only be using it to install windows 7 and Microsoft Office and so can't justify spending that amount of money on a thing that I would hardly use. Your assistance would be greatly appreciated
