I have a Revo 4000 for sale. It has been used less than 1 years old. I have all the original tools and manuals. I even have all the original strings that came with the machine. The machine has been calibrated every 10 rackets and I clean all the parts (gripper, clamps, post) every 5 rackets. Email me for pictures if interested.
I have contacted Alpha and they have confirmed that the 5yr warranty is transferrable. Since I had the machine for 1 yr now, there is still a 4yr warranty.
I live in the Los Angeles Area in California and will let it go for $500 pick up or I can drop it off if you are in the area. If not in CA, $540 shipped in the US. If shipping oversees please email and I will give you a quote on shipping.
