Yes to all.
I use Porsche impellers which have the bushing and so far I have had no issues with them other than they take forever to come from Germany at times.
Cartridge bearings and seals are readily available. I use a specially made bearing because of my shaft requirements for the drive hub but anything can be had with money.

Alrighty then, lets start putting some numbers together. I'm envisioning a process where a customer sends the failed WP in, the shaft, cart/seal, and impeller are replaced with a press, clean up, then off it goes back to the customer.
Roger has a resale number, so lets see what 50 sets cost? Labor looks like press off drive hub, pull cart out the back, press off impeller, then reverse. We may need to make a thin press clamp to get behind the impeller. I don't know which side the cart comes out.
This isn't rocket surgery, and we are paying a rebuider for junk work, so lets stop doing that.
I'd be highly interested to see how improved rebuilds would compete pricewise against a brand new pump. Clearly, no new material is sourced other than the necessary components such as bearings and a new plastic impeller.
I find it rather ridiculous that other car forums have minimal complaints about rebuilds, yet a Porsche 928 pump that is rebuilt is like catching ebola.

You are starting to sound like Kibort in the intake manifold thread!
That's what I just did. Since I just got a 32V and want to stick with a stock tensioner, Ed's pump seemed like a no-brainer to me. Porsche sells their pumps for crazy money, Geba pumps have a metal impeller, and Laso doesn't make their pumps anymore. Ed's pump costs about the same as a Laso did and his pump has a few extra safety features, so for me it came down to Porsche or Ed, and it was an easy choice in my mind. I should be installing it next weekend.
Sean, is that the metal impeller that everyone is afraid of? I pulled a rebuilt from 2002 on my 85 and it had the plastic impeller. Still in great shape.
