Avery decoys & heads are not even close to the quality of BF, HC, Dakotas, or Smiths. I know because I too fell for the "you can buy 6 Averys with flocked heads for the price of 3-4 of the other guy's" marketing ploy. Now a few years down the road, it's painfully clear that I would have been money a head to buy the higher quality stuff. I'm in the process of correcting that mistake.
BTW, I once bought some replacement heads from them. I called down and talked to a Customer Service guy directly so they would get it right and to make sure I could get them in time for the 07' season (this was 2 months before opening day). The heads arrived 8 MONTHS LATER, and were the WRONG ONES for my decoys...
Keep an eye on eBay, if you want to score some Avery shell feeder heads cheap...
Like BJN, I'll give Avery credit for some of their stuff. They make/sell good blind bags, slings, and guncases, and decent blinds, but I will never again waste money on any of their decoys...
