I would really appreciate it if some of the experienced stringers on these boards could weigh in. After extensive reading on Talk Tennis, I decided to buy a home stringer and opted for the Alpha Pioneer DC plus for the following reasons: - Great mounting system with fixed clamps and a linear gripper - Great customer service (This turned out to be true) - Widely regarded as a great machine - Many people said that a drop-weight machine isn't that much worse than a crank and it wouldn't take much more time to get used to it (I categorically don't agree with that) Well the first time I was stringing the screw (6x16 set) that holds the drop weight in place (at the resting position) got sheared off. I waited a few days for Alpha to send me a new bar assembly (which I am really thankful for) and installed that. I was mystified that the same screw sheared off again on the new assembly on my third string job!! I also hated the drop-weight tensioner when stringing with poly. It was just very hard to figure out how much string needs to be fed into the gripper and the string kept sliding out of the fixed clamps. I have decided to abandon drop-weights altogether and get something different. Note that Alpha offered excellent customer service to me. Mark Gonzales was very helpful and agreed to take the machine back and even sent me a return label. I am however looking for a reliable product that fits my needs and I narrowed down my options to the following: 1- Upgrade to the Revo 4000 and trust that this Alpha machine is not going to break down on me. The crank will be much easier to use according to Alpha. 2- Keep the Pioneer DC and buy a Wise Tension Head with a bracket. Not sure how easy that would be to install. How much better would this option be over the Revo 4000? 3- Buy an Eagnas machine with an electronic tension like the Combo 3800 which seems to be a very good deal. Now I know a lot of people don't recommend that, but if the highly acclaimed Alpha machine broke down, wouldn't that lend truth to what Eagnas says on their website, that they basically import the same machines from Taiwan as the other importers and sell them cheaper? Thoughts? Thanks again!
