Oil pump replacement

What is the best oil pump that will last years to come? I am looking for an oil pump and don't know what the best brands to choose out there. I know they can be expensive, but before I put money down and I am looking for high quality, something that will last me like the thirty year old original part.

I need an professional opinion here. I would appreciate it. I want a part that is going to last me along time without having to change it in a couple months to five years.

Thanks
