I use a Gitzo carbon fiber Tripod and a Really Right Stuff BH-55 Ball Head with Really Right Stuff L-Plates for my camera bodies. They are not cheap but you get what you pay for. Quality far outweighs price. The first time an off-brand piece of equipment breaks on you in the middle of a shoot, you will wish you spent a little more to buy quality.
You could always buy 2 of the same off-brand to have a back up, which will probably cost the same as buying a well known piece of quality equipment that will last longer and work better. Just my opinion.
