I work for a commercial roofing and sheet metal company. We used to buy Honda's but our equipment takes a beating on the large construction sites we are on. So, we started buying the predators from harbor freight thinking that at 1/3 of the cost we'll treat them as throw-aways. We now own 4 of the 3,500 watt ones, 57 db and have been rock solid. The 1st we bought is only a year old, so I don't really know about long term reliability but for under $700 bucks I've been pleasantly surprised. I also hear good things about the Champions. Good Luck!
