tow dolly brakes

im going to buy a tow dolly what kind of brakes are the best mechanical or electrical ( big difference in price)

I like electrical brakes on trailers, especially in the mountains. I've owned several trailers, never a tow dolly, My present tandem axle dump trailer has electrical brakes. Going down a mountain grade with a heavy trailer with surge mechanical brakes can be a problem.
