I saw this on CL and actually pursued it somewhat by communicating with the supposed seller a couple times, did some research on the company on the internet and also looked them up on the Better Business Bureau site which they claim they have an A+ rating with. I also did some research on their domain registration. None of it leads anywhere. They are "invisible" ie, non-existent.
The saw is new as is the Husqvarna version they have listed on their website.
I am 100% sure that no one will ever receive one of these saws after sending in their $600.
Another clue is the type of payment they require. I wonder how many suckers they reel in per week?
