Jeff, thanks from bringing this up.
I have a similar dilemma.
Need a replacement pump- and don't know what to choose.

I have been looking on ebay for 3 brands:
- Bosch - Most expensive, but doesn't seem to come with seals
- ACDELCO - Name seems to be more established, not sure why
- SKF - Name seems to be more established, not sure why

Usually you pay for what you get- these brands are a bit more expensive than the others offered on ebay.

Don't want to hijack Jeff's post, but thought its relevant....
advice on quality / best buy is most welcome

Tx Tom
