I have used refurbished Canon print heads from China with no problems. I bought it because the seller had a 100% positive rating on ebay. The IS ink seller everyone praises do not even have a 100% rating. I would buy refurbished print head from China again if I ever need one again. It's not as cheap as you might think. If there is not a new one from Canon available you have very little choice anyway.
No one else makes Canon compatible print heads. No one makes copies. That is a fact. Canon does not sell refurbished print heads. That is another fact.
By the way you really never know if people really got cheap deals or not. It happens all the time. I once had a purchase of an equipment at $2000. The seller said he happened to be traveling near me and he offered a free delivery. The free delivery offer came after I won the auction. You really never know about people. A commercial delivery would have cost me hundreds of bucks. The guy drove across at least 2 US states to make the delivery.
