Aftermarket power steering pump?

I have replaced power steering pumps on my car multiple times. I'm on my 3rd or maybe 4th pump. Granted, this is during a 15 year period with like 8K miles, but it's just one of those thorns in the flesh. They always seem to end up leaking. It's a federal pump. I've used recycled off a running car and I've used remanned. Does anyone make a nice aftermarket one that people have used? Searches didn't yield many results.
