My personal recommendation is this: Since you are just starting bjj I wouldn't recommend going out and spending $150 on a Howard double weave..... yet. On the other hand I wouldn't recommend wasting money on any single weaves (they wear out fast and stretch a lot during training).
I would advise you get a gold weave, they are a good starter gi. Both Atama and Ouano both sell good gold weaves in the $70-$80 price range.
