Not looking to purchase a fine shotgun...but for what it's worth dept. In 1968, I purchased a B grade skeet 20ga for $150. For five years, I shot competitive skeet. After skeet, I hunted quail, pheasant and doves with this gun for 40yrs. Realistically, more than 25,000 rounds went down the tube in the years I owned the gun. (My brother owns it now) through the years, the gun NEVER misfired, or failed to feed. Keeping it clean, and replacing the gas seal every season no doubt aided in the reliability. Speaks volumes for an inexpensive shotgun.
Good luck selling your gun.
