Thanks for the reply, barry.
Is there much to worry about buying a second hand crank machine? Is there anything to look out for?
My concern is that I live in Asia, and I have great concerns about backup service. I'm not sure if Alpha has a service centre here. But I guess there isn't much to worry about so long as it's not an electric stringer.
If you purchase a mechanical machine like a drop weight or a crank then there are very little that can break. If the crank breaks, or a clamp goes bad, you simply remove it and mail that part back under warranty. Most companies turn it around in under 10 days.
Doubtful you will break the stand or six point mounting system, so sending parts is much easier, faster, and cheaper than sending the entire unit. 90% of the weight is in the base / mounting system. Main moving parts on stringing machines are the clamps and tensioner.
After stringing well over a 1000 frames and in all that time (8 years), one clutch spring broke on my drop weight. Replaced it for $14, I did not send anything back to the manufacturer, ordered the spring and it arrived in 4 days. Crescent wrench and a screw driver, and a few choice words, and it went back together.
On a used machine like a Revo 4000, I would try and get one that is less than 1 year old. You can usually find one discounted $100 or $200. Many times people decide stringing is not for them or update to a more expensive machine. Shipping could be expensive, not sure what rates are from the states. You might talk with some local tennis shops and ask how and where they purchased their stringer.
