I always wanted the best for my business in photography.  And of course I”m also conscious of the cost of acquiring the best equipment.  I think it’s exactly the same in any business endeavor.  You want the right tools at the right price.  A musician also demands the same like these zoom accessories from guitar center.  Because if you’re spending all your time and money replacing items that are not the best, you’re wasting time and money that could be spent on the best equipment.
