Motor shield vs H-bridge for a beginner?

I want to make a line follower robot, based on differential drive. What should I buy, this or this? I was wondering.. as a beginner, is it easy to build the H-bridge for the L293d, or should I just buy the shield? The price difference is only ~2$ and I wouldn't want to miss all the fun, though :smiley:

I took the motors from a cassette, so they work on 9V.

Right now I'm just buying the pieces I need, they take up to a month to ship.

Thanks a lot!

Well it really depends on how much your enjoy building a board I think!

But bear in mind the board is a knock-off and you should consider buying the AdaFruit original
