is this kit any good

If you want to buy pieces separately I would recommend PM752 - http://www.slidesandballscrews.com/p...ml?cPath=44_97
and some handsome 500W toroidal transformer (eg from Farnell- free delivery on orders above £20+VAT) + 25A rectifier bridge + big capacitor (voltage not smaller than DC after rectification).

I agree with getting PM752. I have also got them and the extra voltage will help with your motors torque/rpm.

I'm only using an 8A bridge rectifier, with 4 motors it's fine. Just get whatever's cheapest ...

The following capacitor from farnell is good value:
