I just bought a Bosch waterpump, and a crappy Autozone alternator, BUT it has a lifetime warranty, so I'm not too worried.
Pros: lifetime warranty
Cons: crappy

I wasnt planning on changing mine either when i bought my Audi TT and it had 61k miles on it and was just going to change belt and then at 100k the pump+belt.. when i took the pump off to see if it was plastic impeller style the impeller wasnt even attached to the pump.. it was just free spinning on the shaft.. i to this day have no clue how the car never overheated before that day.. cause i drove the car 2600 miles in 9 days prior to doing the timing belt. ill dig up the link but i posted a link on here of a movie how i could flick the impeller and it spun like 6 revolutions on the shaft without the actual shaft moving...
Pros: impeller free spinning
Cons: impeller not attached
Vehicle:
Audi TT
Mileage: 98160 km
Just following up on this- I replaced the water pump and that appears to have resolved the issue. I have been monitoring it frequently and there has definitely been no sign of coolant leaking under the car in the area it was doing it from.
Pros: resolved the issue
Cons: coolant leaking
Vehicle:
Volkswagen Jetta
I ordered one from MJM Autohaus, a Hepu unit and its impeller is metal
Pros: metal impeller
Part number: P525
the aux water pump is leaking you can do it without taking the intake manifold off thru the driver side rear if the engine shouldnt cost you more than 200 when your all done
Pros: do it without removing intake
Vehicle:
Audi A6
Further, the metal unit (Graf) had a sort of reptile-skin texture to the impeller fins, no doubt a product of the casting process. I spent some time with a dremel polishing the fins (because that's how I roll ) to get them as smooth as the plastic ones being replaced.
Pros: smoother than plastic ones
Cons: reptile-skin texture
Mileage: 98000 km
My original plastic impeller pump failed at 145k miles. I replaced with with a metal impeller pump (Hepu IIRC).

I bought my 2001 Jetta with 80k on it. It came with a broken water pump (plastic) plus 6 belt valves and a quarter of the teeth missing from the timing belt. The pump was in about 30 pieces and the damage to the valves was do to the water pump.
Cons: broken water pump, valve damage
Vehicle:
Volkswagen Jetta
Mileage: 80000 km
