Nahhh, I don't think I would rent anything either. Now maybe if you are a guide and you have high end customers that would rent the equipment you may be able to recoup some of your money back, but I think the regular folk like me, would prefer to purchase their own equipment. That way you know how it is going to perform on a day to day basis, whether it is cheap or expensive.
Beside's I wouldn't want to rent really expensive equipment.... I would be afraid of tearing it up and having to pay for it.
