Something else I always do is as soon as a buyer says they will take a item and we agree on a deal is in the for sale thread I post SPF to (there hide name). If anything changes it's already there for everyone to see. I leave that way until I receive payment and the buyer receives the item then...
I had one a few years ago and they are not bad. I would not compare them to a high end scope but for the money they are not bad. I never had any problems with mine but at the same time I would never go shoot a big match with one.
