Use the Porsche water pump only, with the plastic impeller, the metal impeller will tear up the engine block if the bearing fails. There is a fellow on Ebay who works at a dealer in Florida, and sells parts on the side, his prices are really good and he was excellent to deal with his Ebay name is mbofmelbourne, just make sure that you get the 996 pump if that is what you are after as the 997 pump is 2mm larger and will not fit.

Jake categorically states NOT to buy/install the metal one. I attended his meet and greet last year where he discussed this and many other 996 issues. People who attended will back this statement up. He has also mentioned several times in the 996 forum the danger of metal blades. Jake only mentioned he had investigated a repair but he recommends his engine rebuild clients replace the water pump every three years with the Porsche OEM plastic pump.
Here's a comment he made on it: https://rennlist.com/forums/11039659-post4.html
Irregardless if someone has the ability (shade tree or pro) to fix a f**ked up internal casting bore that the pump fits into - its an example of a failure that even the 928 guys acknowledge that plastic blades are the way to go and are investigating a supplier: 'We have a few folks working on a fix, Roger is working on a deal with Lasso for a new pump with a plastic impeller, I think that is going to be a very good choice for many people.' (not sure of date of this comment).
This procedure has NOT been demonstrated on a 996 yet, nor has a tool been built for it to be used on a 996. So its still a theoretical repair on a 996 until we see that post and those photos. Its also not an 'easy procedure' (subjective term) given the % of 996 people who even work on their own cars.
The back story to this repair is that a plastic impeller was not available to the 928 community until 2008 (OEM) and 2010 (aftermarket). Many 928 owners had damage before this availability - hence the ingeniousness of the people involved in this repair procedure. I salute them.
But that doesn't dismiss the fact that there IS a solution for 996 owners to prevent a complicated repair like this one - BUY the OEM plastic part - install it and treat it as a maintenance (replacement schedule) item as per the manual.

Thanks for all the comments. Yes, I am leanign towards OEM, and I have ordered from suncoast before, I can't believe its' $299 there, and $471 at Pfaff.
What else should I do while I am replacing the waterpump? Thermostat?
I am doing it more as a preventative maintenance, it has been 60000km since the last one.

In order to remove the water pump from the bottom you have to remove the hose to the thermostat which is a good portion of the effort to remove it completely. It only takes a few minutes to get the 4 bolts off the thermostat and remove it so I think it is a good idea to replace it at the same time.
Apparently it is possible (from someone on this forum) to remove the water pump from the top by removing one of the idler pulleys but I didn't go that route.
I replaced mine with a low temperature (160 degree) thermostat after researching on this forum. I think the consensus from the experts was that the lower thermostat doesn't hurt and there is a chance it helps. Unfortunately the usual sources of parts didn't have a good price on the low temperature thermostat but I found a great deal at Paragon Products. The owner also has a set of copper exhaust nuts which should help prevent the muffler bolts from seizing (if you are planning on removing the exhaust in the near future).
If you do order the thermostat from somewhere make sure that the gasket is included.
