I have multiple barrels from Hooper in 9mm so I can't speak for their G20 barrel. They were all priced right at around $60 and function fine. I have no complaints. For less than what they want for the G20 barrel, I can get a nice 10mm barrel from Lone Wolf, Spinta, or Double Diamond. For a few dollars more, I can get a Zaffiri, KKM, Alpha Shooting, or Glock. Granted, they may not come in Bronze and that could be the tiebreaker for a specialized color since you will have to send off for coating.
