I am thinking about making an offer on an Eagnas Hyper 480 listed in a store on a certain auction site. I know it's a gamble, given their customer service track record. But I might be willing to risk it if the price is right, and the quality of the machine is acceptable. So I have a couple of questions about this machine, and other similar Eagnas machines. First, are their clamps of decent quality (http://www.eagnas.com/maxgen1/pn1012.html)? To me, this is the biggest factor in my decision, because if they're not good, I don't think you could count on replacing them with some from another manufacturer. Ultimately the tensioner is likely to be replaced with a Wise 2086, but I can't afford both of them right now. So the tensioner would have to suffice for at least a year or two. So I'd also like to know about people's experiences (good or bad) with their linear string gripper and the crank tensioner (http://www.eagnas.com/maxgen/mcstens.html).
