What are good stringing machines?

[brianstover]

I have never strung before but I am looking for a stringing machine to start stringing my raquects and my friends. What are the different types of stringing machines and what is the price range? I have seen stringing machines advertised as new for 200 and some over 1000 but is there any difference to the strung raquect? So basically I need a stringing machine that will string very well and not cost too much.

First of all, it's the person who strings the racquet who determines the quality of the string job, not the stringing machine. A good stringer can compensate (to a certain extent) the flaws of a bad stringing machine, and a bad stringer can produce the worst string jobs on the best stringing machine available.
Criteria you should look at are the quality of the clamps (they should not hurt the string), the mounting system (does it avoid distortion of the racquet) and the tensioning mechanism (how frequently does it need to be calibrated).
While you can achieve perfect string jobs with a low-cost machine, the added value that the higher priced machines are offering is mainly comfort and speed.
So, for a low volume of racquets to be strung, my recommendation would be a drop weight machine with good quality clamps and mounting system.
