Craftsman CompuCarve Computer-Controlled Compact Woodworking Machine Review

Purchased the craftsman compucarve from sears in april 2009.  Carved several small projects and came out just fine and was well pleased. Purchased the umbrella stand from carvewright and made one. Total of 20 hours carving time.  Started on second stand and was 80% finished when it gave the z axis 380 error.  Contact with LHR and they walked me through and it had a bad motor.  They sent the new motor and I installed it on the machine.  Started a new carve on the stand and was half way thru when it lost all power.  LHR advised that it must be the power supply.  I decided it was time to return to sears and they gave me my money back with no hassel.  This was on Sept. 16, 2009.  I still like the machine and am thinking about buying another at a cheaper price that what I paid for the last one.  Anyone that has a machine and would like to sell please advise.
