The tensioning of the tape drive is important and can make a difference in sound. Some Galibier owners like less tension, some like more. Setting it is not difficult at all. A simple nudge of the motor pod one way or the other is all it takes. You will not find any belt drive system that works as well as the tape. It can easily approach the results of any idler drive with no added vibration. Speed is very important with any music, but more so with rock and jazz.
However, it is to the advantage of any Galibier (and Teres belt drive) owner to learn how to splice the mylar tape in order to make a belt. Galibier does supply several and those will last a while.
A roll of mylar streamer is about $5 and splicing tape may run another $10, but a roll of each will be a life-time supply. Otherwise, one needs only a good craft knife, a piece of glass about 4x7", and some postit notes. It takes less than a minute to make the splice once you have done it a time or two.
On a side note, I understand the desire to have someone setup a table for you. In the long run it will be much more to anyone's advantage to learn how to do it. Thom Mackris of Galibier, as well as other owners, can help tremendously with this.
Good luck in your search.
