My best photos yet..

100% happy with the quality and value of this package. Besides, it's quite attractive too. Also, I purchased a mount which needed to be replaced, all the shipping fees did not come from my pockets, and delivery of the new mount got here in less than a week. OPT has given me awesome service, and if they continue to do so, I will continue to purchase from them.
