Hi Fred, in answer to your questions in order.
1. There is no extended warranty
True there is not one offered through Sears some folks purchased what 'on the surface' appears to be one but as of yet to the best of my knowledge none of those individuals have posted a 'successful' follow through using it.
2. They, Sears, do the repairs- that is incorrect, to date only LHR does the repairs.
3. And the only reported problems have come from those who try to use the router in a "Commercial Enviroment"
This is also incorrect- several here have used them as accentuations for a commercial setting, others have looked into it. For me I'm just a hobbiest and honest to God woodcarver. I just felt that the marriage of wooddust and computer graphics was too much not to take get involved with.
I have only 6+ hrs on my machine that has been doted on and through no fault of my own the board sensor went out. Ok- its getting replaced and I'm very happy so far with the customer service I've gotten.
Footnote- Today I'm replacing a hd on my daughters Presario laptop she's had for only 2 months, it went out too. Things happen.
