The eStringer falls into this category. I owned the FL as my starter machine, and it takes quite a bit of tension drop for it to start the repulling process. As a starter machine the overall package is pretty comparable to the other cheap machines out there. Clamps are solid, tensioner is OK/good for what it is. Due to the (relative) complexity, expect it to break down faster than other machines in the price point (drop weights).
I thought SP went out of (stringing machine) business? If you're buying used you could get it cheaper...
