Shaun, agree with Lee unless you need a BRCA approved LIPO, go for turnigy. I recently bought 4 shorty lipo's 2x 4100mah reedy & 2x 4200mah A Spec turnigy's. The turnigy were £20 each the reedys £72, reedy's slightly better built, but performance I can't see any difference.
I am at calidcot tomm night come and take a look at the turnigy's, very very good for the cash!!
