I avoid PCPacific - REALLY expensive shipping.
PBTech I avoid too because the Wellington shop owner is dodgy as... Tries to sell you shit that's supposedly 'top of the line', tried to sell me a 6200TC said best graphics card with TurboCache up to 512mb.
the owner is algoods, hes friendly and tries to help, but the younger guy who might be his son is a complete dick, i rang up asking whether they had a certain monitor (which was on special) and he said nah they dont have it, so i go to the store and there he is showing it to other people in the store!!!
and avoid nz oc zone, i bought my pc parts there and although its cheap, they take about a month to realise you've even made an order, then they say they can't get these parts and try to sell you other crappy stuff.
