Wouldn't you know it, my hand pump gave out after two fills on my new rifle. The pump is about 18 years old tho. Anyway, I was just trying to decide if I should go with a Hill pump from AOA for 200 bucks, or a Yong Heng. While researching the compressor, I found a couple of Ebay sellers in Cal. Anyone know if they are reputable and sell the real deal and not some knockoff? One sells for 250, one for 285, free shipping from both places. They are advertised as Yong Heng, just don't want to get a knockoff. Thanks---
