In the end, it is all a matter of what YOU find most pleasing. There will be arguments on all sides - belt, idler, direct, etc. that are all very convincing in their own way. Of course, the only real way for YOU to know is to listen. Any and all of the approaches can work exceedingly well, IF well executed. If it is a design philosophy that most interests you, pick the one with which you agree most and find the table that executes it best. You will then most likely be well pleased. I have heard idler wheel, direct, and belt drives in my system - with widely varying budgets - one or more of each type with which I'd be happy to own forever. You can find what pleases you - just don't absolutely equate price to satisfaction.
