Best place to buy power steering pump?

[Lattimer]

I have 2 different pumps floating around here. 1 is very noisy, and the 2nd started leaking.

I tried getting just a pump from NAPA before and installing one of my reservoirs, and their pump was louder than the bad one I have and I could not get it to stop leaking.

I'd prefer to get a new one rather than a rebuilt (if possible), and I 'd like to have the reservoir included. Anybody had success?

I tried the local places and nobody has one with the reservoir available. I saw pumps on GMC Paul's, Classic Parts, and Classic Heartbeat. Just looking for somebody with some feedback.
