I thought the composite water pumps WERE the plastic water pumps...

there are also two types of metal pumps.
the one sold at eap4parts is cast. these can fail as well (bearing failure), although not with the same frequency as the old brittle plastic ones (shattered impellers).
for a short time bmw made pumps with stainless steel impellers. these were good. my guess is that this short run was a knee-jerk reaction to the reported failures of the previous brittle plastic ones. the stainless ones have now been replaced by the composite impellers (more cost-effective to manufacture, but with comparable durability to the stainless steel).

whats the fastest way to tell if your still running a plastic one, cause I just bought the car and I'm not sure if this was something that was fixxed or not

BMW makes the best waterpumps (NOW). I only paid around 60 buck for mine from BMW. Just find one of your friends who can get a hold of a sellers permit and you get hooked up PHAT at any BMW dealer.
Just my two cent.
