Go with the Meziere HD. It's tried, proven and not that expensive. This is not the place to scrimp.

me too. in hindsight - it was a big PITA to make the mod (pulling off the timing cover to remove the water pump drive shaft) I wouldn't do it again if I was starting all over.

These sets, in my humble opinion and personal experience, are not very good quality.
And then I am going to remove the water pump gear portion, and use the ED chain etc, and put in a Miezre.
The Miezre has a larger motor and better seal. This data I gathered after researching the same issue of going to a Electric water pump.

I've had my Meziere HD for almost 5 years now, no complaints! The main thing is to get a good relay, I went through 3 relays. I also upgraded to a Cloyes double roller with my last engine build since I eliminated the stock waterpump drive.

What relay did you end up with?

I thoght electric water pumps were track only type stuff? Now its been a long time since I read anything about them (7 or 8 years) but last I heard they overheated like crazy and frequently failed? I guess this has changed? Can they stand up to everyday abuse now?

And also a good relay connector. I thought I bought a good one, it was a Borg-Warner, looked well made with heavy enough wire leads, etc. But I was popping relays every few hundred miles at first and I know I was using good relays. So I finally built my own connector and installed a new NAPA relay and have had no problems for many thousands of miles since.

Yeah--1000 mi I don't think will tell you anything. I still suspect just a bad mechanical waterpump in conjunction with a very marginal gear (hardness is marginal--ok perhaps if the pump bearing is perfectly smooth).
What would tell us something is the hardness in the tooth area of a 60,000 mi ED gear or if we all have bad waterpumps. Mine is completely seized now, and sometime I have to have it pulled apart to see what's in there.

Others might work but if you look at the other connectors in your engine bay, they are all weatherpack, I gather to prevent corrosion.
