i had the same problem, and i will always tell everyone who with - walkerjet - 3 months and threats of court action for parts, the the issues over waranty (yeah right, what waranty), that way hopefully they will go under and the better manufacturers will survive
However
After asking around i eventually bought a nice new Fresh Breeze Monster, and i have to say that Piers (fresh breeze dealer in uk) has been fantastic, the motor is reliable (touch wood) and i do not have to worry about it, any parts sent have arrived the same week (i had an issue with the silencer wrap and was sent silicone sealer and tape the same day, and didnt expect it) i had a spring come loose in the started and recieved a new one the same week - all i asked was how to get it back in.
So i would say that not all dealers are the same, however there are some bad ones out there
i did ask for a rating page so that we could rate our experiences with each dealer but it seems that its not workable, we do need something to make them accountable
