I have ordered hand selects for most of my purchases that I could not perform in person. Most of the time I have been very satisfied. Its kind of like insurance. Its not going to guarantee you get a excellent example, but it may endure you don't get a dung heap.
Some places charge $20 -$40 for a hand select. Add that to a $69 Mosin and it becomes a big part of the price.
I advise you to buy in person where you can. Some of the sponsors are close enough to drive to within a few hours, or they tour the local shows. Build a rapport with them and they may point you to a good one. Plus they help support this wonderful site.
