Only because I was on a very tight deadline did I feel the need to return the unit.  If I didn't have to go out and purchase unit locally the seller seems reliable and did their best to resolve the issue but I was already behind schedule on the project.  So time didn't allow that luxury.  Had we been able to I would have loved this unit.Gorgeous look to it and potentially very powerful.  I have non issues with the seller.  They did the best they couldunder the circumstance.  It happens.
