I do not. BUT, I have heard that the Evans pump is probably the best on the market. It has more vanes and a higher vane height than almost all of the the pumps out there. Also it has a air bleeder petcock installed on top.
My Napa has been working fine, but I currently have the front cover off for a cam swap. I am thinking of this upgrade.
The Evans pump is like 185$~ish...
I am sure you can fine hundreds of links, but here is one..
