Hello all. I would first like to say thank you for accepting me to the forum. I'm looking to get into pcp rifles and I'm thinking of starting with a way to fill and refill these guns. I want to get straight into the compressor route as pumping for several minutes at a time does not interest me. I would like to purchase a yong heng compressor preferably from Walmart where I can get the extended warranty seeing as they are a authorized distributor. when searching Walmart I get 4 or 5 results for yong heng. Two listings say authorized dealer and the other do not. If i click on the authorized dealer I don't see any option for the 3 or 4 year protection. If I go to the other listings it does have the option for the extra protection but it says they are Techtongda brand? I'm soo confused. Anyway do any of you know if these are real yong heng and which one would be the best one to purchase? Thanks in advance.
