Which brand AC compressor to buy if OEM/Denso are not an option?

Question

This is for a Honda, specifically a 2002-2006 Acura RSX or 2001-2005 Honda Civic SI (same part number). I've searched and the consensus is always to go with Denso who is the OEM supplier, but Denso does not seem to be available aftermarket, and it's discontinued through Honda. My RockAuto options are GPD, UAC, Four Seasons, TYC or Nissens. Prices are all within about $30 from each other. I'm open to other suggestions where to buy one, but also hesitant to buy one from a junkyard/salvage supplier. Any thoughts on what I should do?
