I recently experienced and issue with the motor in the X axis. I decided it was best for me to upgrade to the Shark SD120 which is an identical unit. Since I have no use for the Piranha so I am offering it for sale. As far as I know, there is nothing else wrong with this unit, I was using it successfully right up until the time that the motor failed. I am willing to sell this unit for $100 but be aware that it does have this issue. I also have a 4 watt laser attachment that I will sell for $200 since I don't need it either because I purchased a 7 watt. With a little effort and a new motor, this unit should work well for you. I will have to charge actual shipping fees and I have no idea how much that might be. Let me know if you are interested. I just don't want to throw away a piece of equipment that might be very useful to somebody out there.
